I've owned this for about 7 or 8 years...basically from since it came out.

The best thing about it obviously that it enables you to add sounds to your guitar that simply couldn't not imagine before...and it can be damn handy.
The worst thing is that the tracking is slow and ghost notes can occur. This means that if you're not careful or you go too fast or strum too hard or not hard enough then you will get weird notes that were not quite desired. You can set the sensitivity of each string, though, to avoid this in most cases...takes some attention.

This was the first MIDI guitar system i tried and it's not surprising because before this there was virtually nothing. I think there was maybe the GR-50 and GR-1, and they were slower etc. This one could have benefitted from the expression pedal...you get with the GR-20 ! But you can always add your own i think.

Beware that the female output jacks are laid out & shaped in a way that will NOT let you use Neutrik jacks. You'll need something thinner!

The sounds in this are quite amazing, although i wouldn't use most of this for anything else than impressing the mates...
If you're careful, you can use the synth pads (which are VERY dynamic) to great effect, and if you put them through a good effects processor then you've got some fantastic sounds at your fingertips...
You can also use this as a regular MIDI expander for your existing keyboard! You can have 2 layers going at the same time, which is pretty cool. I used this with my shitty PSR-90 to make it into something acceptable.

If you have a Godin LGX (midi, electric and electro-acoustic separate outputs) you can have your regular electric mixed with the electro and then have a piano with strings via the GR-30. Now THAT makes a difference!
Also, you can do your solo through your electric amp and have it layered with 1 or 2 wild synth sounds.

Overall, i think it was a very expensive piece of equipment (i paid 4150 Francs, ie 625 €) but second hand it's probably quite a good deal now. If you use it. And put your mind to it, you really could!

The piano & organ sounds are quite good, the double bass sound is not bad either, and if you stick to the middle of the range you can use strings & trumpets and even trick people into making them think they're real.

Peavey Solid State Professional Bass Amplifier.
Although the DeltaBass of 2000 offers only 160w. Anyone that laughs at this amp is probably
very inexperienced. Sure there are amps with more wattage, some are NOT continuous wattage as
is this amp, but few offer "clean" wattage as does this amp.
The DeltaBass has the most needed connections, front and back. A simple "in" for the ax
of your choice, with a parallel no juice "outplug" for your tuner. It also includes a sound
man's favorite, a three prong "mic" type male plug for the PA system input.
Some of the controls are VERY reliant upon the settings of an adjacent control knob. The
DeltaBass has a set of seven twist type knobs that cover equalization and volume. They dip
into the minus and plus ranges effectively.

When I saw the near perfect layout of the DeltaBass, I knew, quickly, that it would be in
my possession soon. Only experience could possibly know what experienced players want. I
think maybe there are some musicians in tow on the design aspects of the DeltaBass amp.
Within seconds I found the perfect tune collaboration settings for the particular song/sound I wanted. The one thing that impressed me the most was; the perfect pitch delivery
from in to out of the amp. No variance because of lame circuitry. I have used many other
amps in my years, never ever have I had such perfect delivery of the bass note. In other words; If you pluck a "C" note in 440, it comes out the rear of this amp in 440. I have had
variances with other amps. This amp has impressive clarity.
I didn't really need the owners manual with this amp. It is self explanitory!

I play a variety of music styles. The DeltaBass is flexible enough to be a switch-style
amp. I have even heard of folks using it for voice. Though it only has a 3+2 effects band,
the range within these controls is more than adequate for a full parimeter of styles.
I use a Peavey 5 string fretless, a Gibson RD Artist, or an Alvarez flat-top Bass to find
the sound I need for a particular event. If I need sustain I use the Gibson's active electronics that are built in. If I need the lower "B" register, I use the Peavey 5 string, for the softer sounds, of course, I use the Alvarez flat top.
Only slight and quick adjustments are needed to achieve my desired output sound. More
lows and less treble are my most common desires for the Country/Blues sounds. While on a
pick-me-up song might need a twist of the high eq. This amp is quiet until called upon.

I've been on a search for the perfect ride, and I think I found it. Problem is- I can't afford it, more on that later. Sabian's Paragon cymbals are made in Canada, just the man behind these cymbals; Neart Peart of Rush. But you don't even have to be a Rush fan to appreciate this line of cymbals.

First of all, I love the size of this cymbal. Its a beast; 22" in diameter and thick, its like 8 pounds so don't drop it on your foot. One you move up to a 22" ride its hard to go back to a 20". Its thickness means you get a really good 'ping' out of it that cuts through like no other ride cymbal I've ever heard.

It also has an incredible shimmery wash that is subtle but definitely there, and can be tapped into even more by how and where in the field you play the cymbal. There is a complexity in the overtones, very musical. I read somewhere that Sabian used a distinctly different lathing technique on the top than the bottom, that might be a contributor to the sweet and complex tones.

This cymbal might be a bit much for those who are used to mellow 20" rides. Its loud, its bright (though not harsh at all), its cutting, and it shimmers while giving excellent stick definition. It's kind of a cymbal that does everything you want without having to make any trade-offs, but be warned it is an overwhelming cymbal.

Now price; this is seriously one expensive cymbal. I haven't seen it under 350.00. Thats a lot of money, but frankly this cymbal does things that nothing in the Hand Hammered line up can do, and outperforms many of my beloved favorites from Paiste. I would like to see this cymbal go head to head with some of the K Kustom line from Zildjian but until then..... this cymbal is worth the money because it surpasses anything I've played to date. Now where's that credit card I have hidden from the wife....

150 watts. (Not conservative at all, trust me.) Open back 1x12 with stock “blue” Fender speaker . This is a “red knob” model so my understanding is that it’s considered vintage. Two channels – Clean and Overdrive/Distortion with a “boost option”. Clean has Volume, Treble, Mid, Bass and Mid-cut switch. Overdrive/distortion has Gain, Boost, Treble, Mid, Mid-Boost switch, Bass, Contour with “tilt” switch, presence. The amp also has a master volume and reverb. Two inputs, one for channel switching, one for parallel channel mode. The amp also has switches for channel switching, or you can plug into the footswitch jack (which was included) to switch between channel 1 and 2 as well as to select reverb and/or the boost function. Effects loop and speaker out jack on the back panel of the amp as well.

The controls on the front are many, but it's fairly straightforward, especially if you are familiar with Fender amps. The "presence" and "mid-cut" controls are particularly useful. The only drawback is that I don't understand the purpose of the "tilt" control. I usually put the treble on 9 or 10, the mid on 0 and the bass anywhere from 2 to 9, and get great clean sounds, or great distorted sounds with a pedal. The amp is fairly heavy. As with all Fender amps, this is built like a tank. You could probably drop it from a skyscraper and it would keep on ticking. I did have to get the rear input jacks fixed for $20 about 3 days after receiving the amp from Guitar Center. But hey, it was used.

This thing is LOUD ! I don’t think 150 watts is an overstatement ! If you go anymore than 1, you’ve got band-mates and sound engineers sneering at you! Also great for out-competing your annoying rhythm guitarist in the volume department! Clean channel is the typical “glassy” Fender clean that many of us have come to love. The treble can be a little harsh, but hey, it’s a solid state! Overdrive channel is OK, but no one usually gets a Fender for the overdrive/distortion. (See my comments under “overall rating.”) I use the “boost” function on the distortion channel via foot-switch as it provides a great volume boost for solos !

- What type of amplification (Tube,transistor,...)?
Tube

- How much power is delivered?
N/A, this is a preamp.

- What connection types are there?
More than you can imagine: inputs, outputs & loops all over the place.
Ins on the front & back...2 output channels with individual settings...footswitch...this is some serious piece of pro gear.

- What are the setting controls, effects?...
Not sure i can count that high...
5 band graphic EQ + 3 band regular EQ, volume, master, rhythm bright switch, reverb, lead drive, lead master, EQ IN/auto/off, lead mode, lead fat, lead bright, master out A, master out B.
10 rotaries + 5 EQ faders. Never seen anything like it.

- Is the general configuration/setup simple?
Yes, same settings as you're used to on an amp, plus some more than you just have to try...nothing tricky.

- Can you easily get a good sound?
Now this is trickier than expected cos you're tempted to fiddle around and the EQ is very powerful. But you can get good sound if you stop messing around, haha.

- Is the manual clear and sufficient?...
Mine was second hand and i never had the manual.

Some say this has the best clear sound ever when used via the direct out for recording. True that it sounds quite good.

The distortion when pushed to the max gives you that endless sustain you've always dreamt of when listening to Gary Moore...

But Mesa/Boogie sounds Mesa/Boogie. You'll probably love it but you might not. Try it!

In any case, the range of sounds you can obtain here is awesome, and we're talking top of the range here. This is no POD or Boss pedal, folks, this is IT.

- For how long have you been using it?
About 8 years.

- What thing do you like most/least about it?
The treble & mids on these are great. Never tiring, fairly detailed, well balanced...B&W have done a great job there: you can listen all day long and never get tired of them.
The bass is not so fantastic simply because the woofers are a bit small. You can't expect miracles from these and on paper they go down to 63 Hz at -3 dB and 53 Hz at -6 dB if i recall correctly. So don't get expecting much at 30 Hz... ;-)
If you want that big OOMPPH pass your way and go & get some big JBL floortsanders...
BUT, place these correctly (ie on stands and far from walls or corners) and sit a few feet away and they can be surprisingly bassy.
So that's the hardest thing with these, really: placement. If they don't sound good, you haven't placed them right. Simple as that.

- Did you try many other models before getting this one?
I listened to some cheap but much bigger Infinity units before i got these, and they had more bass but the bass was out of control.
These, placed right, are tight and forget about distortion: these babies have woven kevlar woofers: turn up the volume and these will rattle the walls.
120W RMS. I pushed my 80W RMS Onkyo Integra 9711 to the max on them and they were fine, even on bassy disco. The walls were shaking, though!

- What is your opinion about the value for the price?
Retail price was normally 3500 Francs at the time (£350 back then, more now since the £ is worth bugger all these days), which would be 530 €. I paid 2400 F (360 €), new.
I'd say the value was pretty damn good. If you want cheaper & smaller, go for the DM 601 S3's. They are half as much and quite a bit smaller but still sound good, although of course they have less bottom end.

For the money, it would have been hard to get better without going second hand. A friend of mine got a pair of battered old JBL 4311's from Barclay Studios...for under £200. A good deal. But they're huge and one of the boomers has a hole in it! So...today, i'd look around the second hand market and probably go for something bigger. I'm currently dribbling over the B&W 704's. Expensive floorstanders...maybe one day?

- For how long have you been using it?
About 8 years, used daily.

- What thing do you like most/least about it?
It looks great, it's heavy (15kg), it has a huge volume knob, it sounds pretty damn good (check out the specs!), it's dynamic, it's got loads of inputs (3 tape loops + 4 more aux), motorized volume & source knobs so you can change via the remote, 4 speakers outs, direct mode, 20dB attenuator for more precise volume setting.
This amp is ZERO HISS. Yes, even at MAX volume. In fact, there is less hiss on 10 than there is on 7.

The only improvements i could think of would be to let you use the headphone out while the speakers are on...and to have a 3 or 5 band EQ. Although it must be said the 2 band EQ does its job musically.

- Did you try many other models before getting this one?
A few, yes, mainly very old or cheap ones. There is simply no comparison: this is by far the best i've ever tried. The no hiss 'feature' is the most appreciated.
I bought this after reading a big comparison review between this and some amps that were 5 times the price. On paper, this was almost the best.

- What is your opinion about the value for the price?
Well, this was 4500 Francs when it came out (680 €). I paid 3170 F (480 €), new. To be honest, paying that much for an amp is a luxury, but built the way it is built one would hope it's meant to last...better to have ONE good amp all your life than several mediocre ones...no?

Problem is that after a year or so, one side started 'going'. I still have the problem to this day: what happens is that, at low volume, one side disappears and you need to fiddle the source selector or turn up the volume abruptly to make sound return. Turn it down again and all is fine until you change source or switch off. It sounds like it's just some dust somewhere but could be something more serious like cracked solderings maybe?
After about 5 years of use, the fuse blew. Possibly due to overheating (i had loads of stuff stacked over it). Cost 55 € to fix (£30) and they soldered up some bits that had cracked because of the heat. The technician told me it was unlikely the problem would ever occur again, so i'm not too worried.

All in all, despite these minor problems, i think this amp is a very good one.

Beware the black model has a PLASTIC front (yuck!) so make sure you get the silver one, which is brushed aluminium and has that indestructible feel to it. :-)
