King Loudness's review"Terrible!"

Marshall MF350
The Marshall Mode 4 was hyped to be a great hybrid tube/solid state amplifier for the heavier metal styles that were popular at the time of the amp's introduction (mid 2000's). It features the following specs:

350W hybrid output
2-amps-in-one design
Dual independent preamp stages with separate ECC83 valves
Both amp types have 2 footswitchable modes
Amp 1 offers Clean and Crunch modes
Amp 2 delivers 2 distinct overdrives

It's claimed to have two separate amps built right in for the ultimate in "modern versatility." Amp one houses Clean and Crunch modes, so it's designed for more low gain, classic applications. Amp two is where things get heavy... this side houses the OD1 and OD2 modes. The amp also features a reverb for each channel, an effects loop and and separate EQ controls for each channel (bass, middle, treble), plus an additional presence and resonance to act as a master EQ control set.


UTILIZATION

The amp is not difficult to set up tones for by any means. It's easy enough to figure out how everything works and get tones going. However, getting GOOD tones won't happen easily. This amp, with the exception of the clean channel (and to a lesser extent, the crunch channel), was possibly the worst sounding Marshall I've ever used.

The clean channel was not too bad. It's honestly no better or worse than the cleans you would find on a DSL or JVM but compared to the atrocity that is "Amp 2" it sounds fine. There was a decent low end and that archetypal scooped sort of midrange tone, with a slightly glassy high end. Applying some reverb got some decent jazz or blues tones, especially with a Les Paul style guitar. The crunch channel had a decent vibe for seventies arena rock if you turned the gain up, or old school blues if you turned it down. It was a bit buzzy and compressed, but not nearly as much as the OD1/OD2 channels.

The OD1/OD2 channels were horrible. Definitely a "what were they thinking?" type of sound. OD1 had absolutely no definition or sustain, and the resulting tone was a buzzy, thin, flat sounding mess. Turning the EQ controls simply seemed to do very little. The amp's default texture seems to be a very piercing top end with a scooped mids... which is like nails on a chalkboard to me. OD2 was basically the same thing... but with even less midrange and even more gain. It had a bit more sustain which was nice for a nu-metal shred thing, but that's such a narrow focus for an amp that claims to be so versatile that I can't award it any points...

SOUNDS

I tried the amplifier with a Strat, Les Paul, and Godin LG (Canadian made guitar that's very similar to an LP, but with 5-way selection like a Strat). It was being used through an Avatar 4x12 with Celestion speakers.

The clean tones were probably my favourite, since they were the only useable sound there. The crunch tones from the Crunch channel weren't too bad, but since I don't enjoy playing AC/DC riffs at arena volume, those types of sounds weren't very useful to me.

OD1/OD2 were a disgrace. They made a DSL401 (an amp I've claimed for years is my least favourite Marshall by a LONG shot) sound fairly good. Everything that was bad about an overdrive channel was present in this amp, sadly. It was buzzy, thin, lacked sustain and gain on OD1 and was FAR too compressed and scooped sounding in nature. It sounded like a can of bees were inside the amp, buzzing away angrily at what the tones were doing to their ears... Using the EQ controls only seemed to make it more compressed and/or piercing which didn't do anything to help.

OVERALL OPINION

Don't even consider this amp. It's one of biggest cases of "false advertising" I've ever seen. "Modern versatility?" Yeah... good luck with that Marshall. This amp does about three sounds total and only one of them is remotely adequate. It's VERY easy to see why this amp gets slammed online, and more importantly why Marshall discontinued it. High wattage "hybrid" amps designed for scooped metal tones never do sound good (this and the Fender Metalhead are top contenders for this award) for anything but bedroom metalcore played at arena volumes.

I give it a 2 because of the at least decent nature of the clean channel only. Otherwise... it's unusable. Stay away!

MGR/Stinkmonkey reviews the Marshall Mode Four's review"Marshall Mode Four Half Stack"

Marshall MF350
I packed up My Gibson SG, Fender Limited edition Fat Strat w/active EMGs and my GNX3 and headed for my local Guitar Center and Sam Ash to check out the 'The Big Amps". It was kinda fun watching them inventory my stuff and fill out the paperwork. This has to be some of the tightest security I've ever seen! I tried every high gain amp and cab combo I could. I mean Crate, Mesa Boogie, Randall, Marshall, Vox and a couple 'off' brands. Honestly, every one of the major brands ROCKED BIG TIME. I wanted a couple of them, but I'm not rich. They all had good points and poor points. I have a Crate 120w combo, but I was after some sort of stack and wanted higher volume (read in Tim 'Tool Time' Taylor type POWER VOLUME). I didn't want to pay for a full stack, but wanted the sound and power. I got it, This was the Amp for me.

The FX loop is way cool. I also like the Amp2 mid three way switch, the EQ mid works with it, both Amps scoop switches work with the EQs too. Having tube preamps means it sounds better loud. This bad boy is LOUD. I chose the 400A cab as to get the full 350 watts from a half stack. I thought the MF cabs easily sounded the best with the MF head, and I tried other cabs because the MF cab is a couple hundred bucks more. I try and get the most for my money. The 400A cab is 8ohms. The 400 cab needs to be plugged into the number 2 plug. The 280 cab in #1 for half stack or both for full stack. There's a chart on the back of the head. This is to match up the impedence of the speaker cab to the amp. The 280 at half stack is 235watts, still not shabby. The angled (A) cab produces a more cutting upper mid and treble that I liked over the (base) B cab. When you 'tweak' the controls for the first time turn the knob quickly from side to side to understand the amount of variation of the tonal control. You can make the amp sound bad to you (to each his own 'bad') by over adjusting the tone from your liking. The Marshall has a definate 'sweet' spot. There is just that much adjustment available in the tones. The manual is available from the Marshall web site. Pay attention to the hints and tips. The balanced outputs for silent recording are awesome. I get the tones through the recorder and don't have to worry about the cab volume. I do have to add bass if I don't mike the cab due to the deep sound of the cab vs. straight to the recorder through the head. I also hook up my amps the the PA and this feature makes it a breeze. I play every style of Rock and Blues and I can get whatever tone I want out of the Mode Four. I also get those tones at extremely high volume. Too Cool

I had to buy a clamp on console light for the head strap handle and color in the dots on the adjustment knobs to see them at low light levels. I think I'll hit my local gun shop for 'dots' like you use on night sights. Marshall should do this. I had to tighten my knobs when I got it. It needs one more handle on each side of the cab as it's heavy. Don't expect your girl friend to help you, no offense ladies, but my wife could really hurt herself tryin' to help me muscle this beast up on stage. The cab weighs in at about 150lbs.

Please, it's a Marshall. It is extremely heavy as it weighs in at about 150lbs.
Seems tough as hell. No major brand of amp I know if is built 'cheap', or nobody would use them due to the high replacement cost.

As far as looks go this is one badass amp.
It's beautiful as well as intimidating. I love the tones and the volume of my Marshall Mode Four Half Stack w/400A cab.
I'm already recording with it. I swear sometimes she....it gives me wood.

MGR/Keith's review"Marshall MF 350 Half Stack"

Marshall MF350
Guitar Center in Danvers, MA for a total of about $2,100.

It's loud! A real meaty overdrive sound that is sure to satisfy metal-heads. The clean also excellent, unaduldtered tone. The reverb is nothing to rave about, it's an eery sort of reverb that gets the job done. I prefer Amp 1 which is the JCM 900 portion of the amp, with the gain turned up and those becoming saturated it's pure, biting aggression that will make your ear drums beg for mercy. It's also a very cool looking amp, and the cabs are bigger than any marshall before, by 3 inches, and certainly bigger than any cab I've ever seen. And it sounds the same at any volume.

The four modes aren't quite independent, the bass, treble and so on work for clean and crunch in amp 1, and for OD1 and OD2 in amp 2. What I mean is that amp 1 and amp 2 have one set of options for two "seperate" channels. No standby, but a "tuner mute" button for silent tuning which I use in the same manner as a standby switch.

Like a rock. This amp is all about power, in its presence, its tone, and its physical structure. Hunks of gold steel for knobs, I think altogether it weighs about 140lbs.

This amp is metallic fury. If you are not a metal-head this may not be the right amp for you.

Marshall MF350
350 watt amp, tube preamp, amplification transistors. So a mix of both.

In after me is the important point of the head, the hybrid!

One gains the advantage of having a very good sound of low volume, as a high volume!
Then, a second advantage to keep a little transistor is not saturated clear sound!

I do not dwell on the possible settings, they already are a retailer!

PRESICION, which seem to me important, the head has emulated output, saving for example, am going out with jack or XLR)

UTILIZATION

The setup is classic, and should not have three years to find his sound.

The matrix is ​​a real tone +, which I think has to adjust the amp and used guitar sound you want.

Nennmoin, I put a caveat, because on Channel 1, the pitcher and the clean sound is not balanced, the crunch is far too strong relative to its clear Daprès me he will make a choice between the two;)

SOUNDS

I was looking for the ultimate in versatility, having already a versatile guiare (PRS CE24

OVERALL OPINION

I own it for a week, but get a good sound was very fast,

What I like most is the sound, versatility, looks, power! Everything!

What I regret is a channel volume level CRUCH Balanced with clean sound. But ...

A 650 € + baffle head 400 watt oven mode, yes I would do this choice.

And if I had to buy new, I would do also.

I was not ashamed of all side lights;)

Marshall MF350
Hybrid amplification (all already been said above)
Transistor and power amplifier tube preamp
In effect: reverb (very effective)
Power 350 watts - it sends configuration sévére

UTILIZATION

not very simple because there are so many possibilities with that of its head
no manual (since bought used)
obtained by well nag, easily a good sound, vintage sound on the other hand is not her thing too, to avoid
But for a treat TRASH METAL

SOUNDS

it is perfect for my style of music: Trash Metal style EXODUS, KREATOR
I play guitar with a EMG 81 Jackson mounted, it rocks viciously
The reverb is really nice compared to other MESZ head amp (Peavey xxl, Bugera 333XL, Randall rh150g3) disto it even surpasses the others, although the BUGERA 333XL is pretty good at distortion guts, but he possessed a distortion over

OVERALL OPINION

only do this one week than I have, I'm always on the ass
Used in the price remains affordable for the upscale home of Marshall, and yet I was not a fan of this mark for large metal distortion, then I'm amazed

Marshall MF350
Hybrid amp head, preamp tube (12AX7), section transistor amp, 350W, effects loop, mono, 4-channel switch solo, reverb.

UTILIZATION

4-channel amplifier configuration (2 x 2 channel amp)
AMP1 setting common channels CLEAN and CRUNCH.
AMP2 common setting OD1 and OD2 channels.
I would rather have four completely independent channels.

SOUNDS

The clean channel (1 amp, channel 1) is one such model. With GAIN control is adjusted warming subtle sound while maintaining a broadband frequency response. The transistor provides amplification due to its capacity reserve keeps a dynamic and frequency response for an incredible amp. All tube amps compress the sound and eat the treble, there is not the case! This is probably the channel clear reference to Marshall (and others!)

The crunch channel (1 amp, channel 2) is just as good. It should exaggerate the gain of this amplifier is then due to the volume of the guitar that we choose the level of distortion. As the lamp compresses the sound on that channel, no concern for volume (it remains at the same volume on 3 / 4 the volume knob on the guitar). The dynamics of the game on the strings of the guitar allows an excellent mix of distortion. This channel has a crunch on the Marshall, but is much better than other amps of the brand with the precise dosage of the distortion. Attention guitar volume background, level of distortion is extreme.

The overdrive channel 1 (2 amp, channel 1) is the classic 4. This is equivalent to a channel saturated Marshall tube amps. No surprise the sound Marshall is there. It still feels a huge reserve of power under the fingers (used only on channel 4).
Using an equalizer in the effects loop allows you to boost bass and treble without the power amplifier is undermined. So you can sculpt the sound at will if necessary.

Finally, the overdrive channel 2 is really the channel is more saturated than Marshall ever made. The preamp section saturates the sound over a wide frequency band. Mid control can work to get the sounds made a very powerful bass. This channel is really new to a Marshall amp and really sets this amp head.

Bafle 4x12 "indispensable, I use a 1960 factory cutaway (not tampered), the sound is softer than the equivalent Bafle MF. Matter of taste.

OVERALL OPINION

In summary, this head is surprisingly sound and power. The choice of a hybrid (tube preamp + amplifier transistor) could discourage me at the base, but the sound is quite the go thanks to the excellent preamp tube. The powerful amplifier section (350W into 8 ohms) provides a record of its broadband, plus the ability to play high and low volume without taint the sound would be equivalent to the lamp.
Channels 1, 2 and 4 are the strengths of the head, the channel 3 is more conventional but useful to keep the Marshall distortion.
Finally hybrid technology has the advantage of being less fragile (same preamp section, but without amplification section power tube) for musicians who are running.

Although the head can not compete directly with a Diezel VH4 head type (the reference!), It has the sound and dynamics Marshall and more. It is really the high end at Marshall, it is not nothing!

I think this is a very good choice. The price is not excessive if you already have a 4x12 "indispensable.
Zerabit11/08/2004

Zerabit's review (This content has been automatically translated from French)

Marshall MF350
Hybrid Amplification: 2 tube preamp, power amp transistor
Power: 350 W (half would have been sufficient)
entered loop "effect, the ability to connect 8 or 16 ohm speaker.
Common setting in two preamps: Master, lead boost, presence, resonance.
2 preamps with EQ.
Preamp 1: the clean and crunch with adjustable bass, mid and trebble for each, volume and gain common digital reverb, key scoop to dig the media (effective).
Preamp 2: Overdrive 1 and 2, same config as a preamp plus an adjustment for restructuring Tone Matrix mediums.
All controlled by a large 6-button footswitch, look really sturdy (notably the cable is baucoup larger than other pedal Marshall).
The config looks good, the whole is consistent, readable, and gives a good appearance quality.

UTILIZATION

As I said just before, the configuration is simple, no need to leave central to understanding the operation of the amp ...
The EQ is effective for a Marshall, there's been progress.
The manual is clear, in several languages ​​including French ... whew
So far, nothing to say, it deserves Sept. 1

SOUNDS

The sound now, which is clearly denigrated by many users of AF ... then go to Caesar what belongs to him.
I said before I use this amp for 1 1 / 2 years with his cabinet MF 400 A, in my opinion indspensable to make the big sound and a Les Paul Classic ...

Preamp 1
Its clear channel 1: Here is the first surprise, Marshall had accustomed us to clean sounds flat, no real dynamic mode oven sounds clear to him really effective. The settings allow to obtain sounds slamming baucoup more and clean (you might say it's good, this channel is dedicated to that) than the other amp in the range, or round and large (with the neck pickup). On the other hand, equalization appears to be effective without being (too) sensitive, the sound really changes when you turn the knobs. 1 point for Marshall to clean.
The crunch channel 2: Small flat for the crunch, to my taste it more saturated than it crunch, I think you get the real crunch by staying on the clean channel gain and pushing the bottom ...
I should point out though that with my guitar and microphone ceramics, perhaps the plateau so the crunch a little too saturated.
The sound is a little too aggressive, it's a metal crunch ... if pressing the scoop, the saturation effect appears even more aggressive and sound can be felt ... The metalheads will be pleased, my personal, I'm not too pleased.
Little note: a separate gain for the clean and crunch would have pauffiner very effective settings and would probably solve the pb mentioned above, in fact, if we use the sound as much like me clear that the crunch, it is necessary to compromise its volume to stay the same for both ...

Preamp 2:
Channel 1: Saturation classic Marshall type can be found the sound of gun'z, Led Zep, it's good rock 70's, 80's or 90's ... Personally, it's the channel I use the most, I find that the distortion is really good and the gain and EQ setting for finding a good sound.
Channel 2: Contrary to what I read, this channel is REALLY different from above, here we are in the den of neo. any chord takes a dimenssion extreme, it's nice when playing alone, baucoup least when you're in groups because the mix quickly turns into soup and low gain, is less precisely not to put too much gain ... then the sound becomes exploitable, large, aggressive and gains in precision. Anyway Personally, I do not like group, but you still have to admit that the sound is huge ... nothing to do with a JCM 900 transistor as I have read, the sound is baucoup baucoup more ... Basically, with the key and scoop the mids and you dig is the fourth dimenssion, we get a sound very modern.
Setting Tone Matrix, I find it effective, little change despite the different positions.

So I think the sound is rather nice in a clean and overdirve, crunch and overdrive a bit disappointing two unusable for my taste (that said, I do not play neo). It was not just the heat of a lamp, it is clear, but the sounds are good and expressive baucoup possibility of following its channels, you just spend time looking for the sound (which I think baucoup have not tried)

The reverb is very effective, the presence and resonance settings can give even more aggressive sound (though the amp was enough like that), and lead can boost it out qd is a solo ... practice
Weakness: gain common to both channels preamp ... damage, I put a 7 in the overall rating because of these connections because I do not like to compromise with my sound.

OVERALL OPINION

I use this amp for 1 year and 1 / 2.
I love his face, aggressive ...
I find the amp much, and I really regret that gain common two-channel ... In addition, 350 W, it is absolutely unnecessary, repeating or in concert, I have not mounted the master more than 1 / 3. But who knows, maybe one day at Stade de France :-)
In hindsight, I think I do not reffer this choice, and now the amp is for sale with his pregnant ...
I put an 8 in global opinion because I think all still pretty cool and fun. I'm surprised to see so many people to murder, it is clear that it is expensive, too everything from the lamp, but it's not a bad amp, on the contrary ...
RaphRaymond10/16/2004

RaphRaymond's review (This content has been automatically translated from French)

Marshall MF350
It's a hybrid amp: a lamp pramp and transistors elsewhere for a power of 350 watts (just history to the gallery a little while 80/100 watt lamp dB).
The effect Intgr just rverbe numrique pretty cool. The connector is divided into two, clean + crunch and distortion each with 2 Gain, Volume, 3 band Eq, Scoop, Reverb. The distortion has three positions in addition to the three (a priori) Different.

UTILIZATION

Config trs simple, it's stupid as a Marshall, and when you turn the knob EQ did not much like a Marshall, but enough so a will. I have not seen the manual, I test in a small shop alone for an hour and a half. It is unfortunate that there is no longer Eq spar between the most distal.

SOUNDS

The clean channel is correct or even good for much more than the average slamming Marshall (but not dynamic is a transistor ...).
The crunch is average and my AVT100 is much better, it is fat, drooling a little, not trs beautiful.
The old school distortion is very well and it is easily play riffs of Led Zep ...
The disto mtal (hihihi) is actually a little more dense, it does not so low, but many acute, however, is trs frustrating, the fact AVT100 also my best. The three mode distos trs are different.

OVERALL OPINION

As I said I tested in store and for that price (1600 + baffle head) I'm afraid he does stand a long time ...
I like the fact that there are four channels for a one develloppe vritable sound palette. (Even if it is a little pourrite, even when it's a pallet).

So I find it expensive for what it is. If you want a big sound while taking the lamp, if your not too demanding and just a little broke and take a AVT100 an 4x12 of quality.

It's a shame because he has a really good face!
