A little confusing at first, EQ treble and bass left to right, is very effective. We must follow the manual says to first 12h the boost function and refine the next sound you want then. This feature is part of the grain of this amp, adding a certain amount of "growl" sound. It takes full advantage of this feature with the bi-amping a speaker Gallien-Krueger. The tweeter is so "clean", unaffected by the slight saturation brought about by the "boost".


Precise, warm, sharp as a razor, and with character, this is the sound of this amp. All watts of record are waiting for you! bi-amp can make the most of the grain by measuring the tweeter amp in my cabinet Gallien NEO 212-II. My instrument is passive, so I set the sound to the amp and everything is there. One might want a parametric mids, but then I quibble!


It is an excellent amp and original design, with a standard diet, and not too heavy (10kg). It is very versatile, powerful than enough to cover most situations of play Top! To get a little better (and still ...), you must make me 2 times more expensive.
