    I am looking mainly good crunch to play a good vieu rock'n roll and clean although slamming crystalin and the palette is great in rglage .... so for the lover of pure rock sounds you'll be surprised.

    After having played on a marshall AVT150 ​​are no photos!
    The difference and instant!

    Marshall EL34 50/50 output + cabinet ORANGE PPC112 = outstanding
    I have been on another pass config as too big, too heavy, too long embtant

    MIDI.
    This is not the sound marshall is more versatile.

    Cons:
    not metalheads, unless they add a pedal boost or additional distortion

    Purchased to manage easily on stage and at the foot a lot of different sounds by subscribing via the multi-effect noon JMP1 and avoid invasive pedalboard.
    I use since 2007, first coupled to a power amp marshall 2x80W 8002, and with a Digitech multi-effects which I forgot the name!
    I will soon add to it a tube power amp peavey classic 50/50, it should not hurt to change the sound!

    I'm pretty satisfied with the JMP, I use only the saturation of the preamp that suit me perfectly (rock / heavy). IN his clear what ets more limited (that ets Marshall, Fender not!), And I find that EQ output is not the luxury to get drinking sounds even with my Strat.

    A headphone facade.

    UTILIZATION

    Very intuitive, each parameter is adjustable via a single knob (endless) settings from -6 to 6 for low, mid, high, 0-20 to gain and volume, the setting of the selected parameter is shown in red.

    Manual, dispensable, can be used for parmétrage noon or recording settings (100 presets ... I doubt the relevance of so many when we quickly turns round with the settings, probably for use with 2 or 3 other midi devices whose settings would complement?).

    Sounds clear lack of definition, treble bite before cristalins, or more precisely, the adjustment is made on a frequency to be loved. It takes effect in the loop for pleasure, otherwise the record is a little ungrateful.
    Not possible crunch.

    OD can be interesting if you like that kind of color, but you can not get out too. It is quickly compressed from one ascends the gain.

    SOUNDS

    Long used with different rack effects (Digitech 2120 Alesis Quadraverb, also tried with a Fractal Audio) plugged into an amp and Mesa Boogie 2:50 (which is much more convincing).

    The effects racks can rework the EQ to find other colors, but trying too hard to distort the original sound is still loses definition. Better get used to really sound very cete medium and a little muddy. A bunch of different guitars (Gibson Les Paul Standard 1990 Strat pickups Duesenberg, ESP ...), the sound is very distinctive.

    I mainly used in metal / rock / prog context, with a rather medium need (that's good). For brit rock it will not work (well, you can do everything of course, but good). For death metal that can suit even if the precise time they seek treble side.

    OVERALL OPINION

    I kept almost ten years, in parallel with other amps. It has served me well, it's just fine for the scene, for example.
    Given the bargain price, it is a correct choice.
    I am separated because the game is a little soft, once you pass the studio it's embarrassing. There are a whole bunch of electronics that eats the game and dynamics. I thought I could get a quick response with all lamps, all-tube heads but I could try for a better offer well made and offer a wider range. The lack of crunch may not pop, but soon tired of the little room offered by both OD.
    With experience, I do not orienterais me to the rack config JMP1 the armature (not always, of course). + 2:50 JMP1 can find 800 secondhand in 2013 for the same price a head allows more things and especially transcribe accurately the game without going through A / D converters average. But it is a little harder to find!

    Tube preamp Marshall

    The (big) sound that people our nights for 30 years. Deep Purple, Led Zeppelin, ACDC, Maiden, ZZTop, it allows all :-)

    UTILIZATION

    Config very simple, 25 presets already allow uncouple the piston!

    Just the name makes you want to scratch all the wallpaper :-)
    Examples:
    07 Angus Ho,
    04 British Steel,
    11-Tej'as,
    14-More Gary
    19-800's
    Y ... z'ont everything, there's only use.

    If that's not enough, you can set any (clean 1 or 2 OD 1 or 2) Gain level you go, the equalization and blind, roll my chicken.

    I use 1x Valvestate 8008 + 1x1912 + 1x TC Gmajor loop.

    SOUNDS

    My style is just perfect.
    Mode is selected (Clean 1, Clean 2, OD 1, OD 2) we sculpt the sound with the gain (0 to 20), The Master (0-20) and the Bass / Medium / Trebble, it refines with the Presence, and a small boost from Bass.
    Note that on each channel mix is ​​adjusted with the volume of the effects loop.
    If we keep the 25 presets can store 74 other profiles.

    OVERALL OPINION

    I do it again this choice with his eyes closed.


    Only downside, it ets no longer manufactured so if Marshall's boys read me please relink it (as is) in case it eventually fail on occasion.

    There are two lamps preamp, the connection is fairly complete. MIDI is for me the best solution for this type of machine.

    UTILIZATION

    sounds are easily editable, simply press the right buttons.

    SOUNDS

    the clean is not evil against I prefer the OD 1 as thinner to play the 2.
    We must balance the mix of effects because otherwise we will quickly towards the slurry.

    OVERALL OPINION

    I quickly realized that without a good amp, this device is not satisfactory. It is right and cold compared to some other amp that I've had the chance to try. It should therefore boost with "good hot" lights and a cab, which in my opinion, must be equipped with ceramic bowl alnico and not if the cold side of the beast is stronger.
    Juggling the parameters we arrive to find good stuff but still need to spend a little time, it's not plug and play.
    Personally I do not do it again this choice because I had something else to taste.

    I played with a rg321ex Ibanez that I replaced the bridge pickup with a seymour jb tb4, balanced on velocity300 Rocktron and 212 equipped with Celestion seventy 80. frankly it sounded really full!

    OVERALL OPINION

    I owned it for four months but can be in regular use (again, concerts ...), I loved all the sounds of the preamp but I am separated for too fragile for my taste because of the time cooling system after use and twelve one bit overwhelmed.

    super preamp

    Marshall JMP-1Published on 06/21/13 at 02:10
    (This content has been automatically translated from French)
    Hybrid lamp / transistor, the best two worlds, fully controllable by noon.

    UTILIZATION

    Setup is very easy, you get quickly and easily a great sound.

    SOUNDS

    the range is quite wide, from metal to blues. on the other hand, for clean sounds we remain in a marshall palette, rather round and not crystalline.

    OVERALL OPINION

    This preamp is almost a must have, versatile, practical and easy, you can still improve its performance by various small mods (mod boost dr).
    The value for money is excellent.

    (This content has been automatically translated from French)
    preamp choice of four channels two cleans two overdrive. adjusting bass medium treble presence and gain volume (all very efficient)

    no effect but an insertion loop very well designed (maximum 12 otherwise it is set in parallel.

    UTILIZATION

    not really need any manual is very intuitive it is especially important to use his ears.

    preamp choice of four channels two cleans two overdrive. adjusting bass medium treble presence and gain volume (all very efficient)

    no effect but an insertion loop very well designed (maximum 12 otherwise it is set in parallel.

    UTILIZATION

    not really need any manual is very intuitive it is especially important to use his ears.

    I play very melodic rock oriented soixantes ten years. What can I say except that this is exactly what wanted. I did not for a long time but I am amazed by the scope and sonic palette of the beast. with a good multi-purpose (for me rocktron xpression and tc g sharp for delays and reverbs can easily (well with a little patience) to approach a sound to the page or go to one of Santana or Gilmour. always with the grain so recognizable marshall. whistle notes, this "feedback" means any one beautifully harmonic chorus. including I love you ... and I'm still at the stage of discovery

    OVERALL OPINION

    I had a ToneLab before very artificial but ultimately
    I also long ago played a Valvestate but I much prefer the sound of the preamp. I plug in a lamp while black heart but often I just go out on the table in the monitor speaker with emulation hp and sounds!
    if only one comes across a good secondhand unbeatable value for money. nothing to do with the more or less synthetic emulation where it lives it breathes but be careful it does not mask the weaknesses of the game .. instead
    what I love most
    sound
    MIDI (I control everything with a Behringer FCB1010 pedal it works nickel)
    different channels
    least
    ben really nothing

    JMP-1=G System=Marshall 100/100= stereo 4x12 cab

    Marshall JMP-1Published on 02/25/13 at 23:01
    we control and use the preamp with a G System, power it with a EL34 marshall 100/100. and run it into a customized stereo 4x12 marshall cab. I mount the 100/100 in a separate rack because I sometimes just carry the preamp out to use with other set-ups. without writing a book, my background is 25 years of playing in working bands, and having said that, I was always hard core plexi and really love the sound of superlead stacks. My old school rig was 2 JMP 1/2 stacks. I later went with a wet/dry combination, in other words I send all the effects to one wet/amp and keep the other amp dry. when I went to the wet/dry configuration, we sometimes used a modified JCM-800 head on one of the cabs. an…

I later went with a wet/dry combination, in other words I send all the effects to one wet/amp and keep the other amp dry. when I went to the wet/dry configuration, we sometimes used a modified JCM-800 head on one of the cabs. anyways long story short, a good friend passed away and he wanted me to have his Rack rig. It literally sat in a corner of the warehouse for 3 years until another guitar player took the covers off the racks to see what was inside and went on and on about how awesome they are and who all uses them still to this day, so we hooked it all up and ran it stereo into 2 4x12 cabs with vintage 30's... literally we all went nuts over this thing... I think anyone who likes marshalls would like the JMP-1 we have had all kinds of preamps over here, and ever since we started using this one, it's really sparked some creativity.

    UTILIZATION

    It's the most simple preamp to use I ever seen. very straight forward it has the typical Marshall stuff, Volume, Gain, Bass, Middle, Treble, Presance. It has an effects loop and you can adjust the mix. It has a bass shift. 2 stages of overdrive, and 2 stages of clean. you can save up to 100 presets, and control it with midi... It has no onboard effects.

    SOUNDS

    Most the night it's reissue les pauls through it. I do a switch and play about 5 songs with a 1963 strat. My pickups are hand wound and read around 9k. the strat pickups were rewound by a old man in Dallas Tx named Vanzandt, he passed away around 1999 I believe... anyways I dont use extreemely high output pickups, so these guitars will sound perhaps a little brighter than some. I change the volume pots in les pauls to 500k pots and although the JMP-1 dosent clean up as much as a big plexi, it cleans up enough for me. With the volume knob you can go from a RATT(or worse) type gain down to a "All Right Now" type tone, and 74 Jailbreak would be in there somewhere also. our music is Power Rock, most comparable to 70's 80's. the tones from this rig without effects is straight-up AC/DC sounding, cleaner settings like Free/Bad-Co. If I add a little more gain, chorus and delay it's totally 80's. on clean settings with chorus it sounds kinda like Purple Rain. With a Flanger it sounds kinda like Pat Travers rig or V-H Unchained. with volume knob technique and a-lot of delay set around the high 400m/s range it will Nail the cathedral sound. one issue I have is you loose a lot of db when switching from od to clean settings.

    OVERALL OPINION

    I like the sound of it. it was given to me, but I would hunt one down if I lost this one, I would probably have to pay around $400. to get one used on ebay todays prices. we have had almost every kind of preamp in here you can think of. I like this one because it sounds good and it's simple. It's not loaded with effects and it wont sound like a fender, which is good for us, but not for everyone... if you mounted this JMP-1 in a rack next to a POD the pod would have a depressive meltdown and cut on itself.
