«  Pretty good helper, very typical. »

Published on 11/22/13 at 12:55
Two lamps preamp for two clean and two types of overdrive which meet soon enough. We toured the sounds available in less than an hour.
Connectors: entrance facade, 2 outputs on the back for sending in the power amp, an effects loop (a send and return for 2 stereo effects), connection noon to manage other devices, Stereo output with HP emulation, switch +4 / -20 dB.
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!
