UTILIZATION

Very easy to use, no menus here and even fewer by menus, as easy as a OD pedal actually.
It is the ancestor of DI boxes saturation, the base is Designed with a view to plug into a mixer without going through an amp and my time, it works very well.

A precision, the guitar is in between instrument and line level signals.

SOUND QUALITY

Of course it's all we are far analogique.Ici product lines 6, the typical sound of distortion of the 80's, many used it, the Rockman was given a big kick in pedals at the bottom of the Japanese 'era.
I had a DS-1 (Japanese) that time and the Rockman got a contribution A veritable "food of some oxygen," finally! distortion in a "box" that sounded.

The sound is much warmer, than I POD 2.0 for example, and without the cot "synthtique.
It is especially Designed to connect directly to a mixing desk (this is his favorite fields) hi-fi sound.
On a power amp or guitar amp direct Pramper, the result is correct but less happy.

Nickel for rock, hard or heavy, the sound can be also very "singing" in the context of use melodic line on a game for example.

The sound is very saturated typ (we like it or not) but inimitable (the guitars on Nougayork Claude Nougaro others) also no models on the Line 6 DM 4 is due! !
If you want the grain so special, buy you a Rockman is the only solution.
The grain is rich in harmonics, complexion medium rather strong but without being loud and aggressive, but rather round with a long sustain and a conversion of the notes in this same feedback contrl and low / average volume, it is very easy to hang a note contrlable feedback.
Triturated can sound "in every sense" but the basic tone color remains sound ,.... Rockman what.
The Distortion Generator comes from the distal part of Sustainor, but its even more extreme in saturation and sustain (if needed) but less plbicit the era as Tom Sholtz (Boston) used the Sustainor.
A classic distortion, availing oneself completely (from my point of view) for a magnet DO DIFFERENT various grains and wanting to broaden range of sounds "saturated".
Its a very typ which may not appeal but in any case it is inimitable, is sure.
I have been using 88 is yet I have two lamp heads Plutt correct.

OVERALL OPINION

All products are top Rockman qualitla brand produced high-end analog products constructed fawn semi industrial ddi specially the guitar.
"All" the scratch of the eighties have utiliss Rockman at least once in their life.

I use it for 22 years and the particularity that I like most is his single grain.
Warning! I RPTE, we like it or not because the sound is very typperso love.
I bought new between 1500 and 2000 .... the ball era!
C'tait "expensive" but 20 years after it works like these beginners, yet believe me, he turned his tourntournet re-sod, as sturdy as the Boss pedals.

For info, thank you for this site Jark, Jark specialist in both the global (and french)
Rockman, approved by him even Sholtz.
