Everything has been said above,
very versatile with choice of lamps amplification: EL34 or 6L6

UTILIZATION

-Configuration simple in theory: 2 channels, 5 modes, 3-Band EQ, presence, gain, master and reverb per channel. With all that was not enough of a lifetime to explore all combinations of sounds (the equalizer varies the sound impressively)
-It sounds at once monstrously good!

SOUNDS

- Suitable for all styles, from blues to hard rock extreme!
- I play with my Gibson Les Paul Custom or my Flying without using any effects except the reverb of the amp. Sound:
-Clean: Crystal clear, clean, clear
-Crunch: bluesy, in the same style that a tube screamer
-Raw: it is a crunch prompted, in charge of harmonics, very raw
-Vintage (my favorite!) Round, warm, perfect for solo to santana!
-Modern: violent! it gains in power, monstrous distortion of high quality (extremely accurate, no snoring), it is the sound Correct!

OVERALL OPINION

I've had it for 5 years and she never gave me any trouble! high-end
-Reverb is very good and colors the sound of the amp so perfect especially for cleans and the overdrive solos (I do not use it for the modern mode)
It value for money is very good even if it is expensive (like all high-end amps)
