UTILIZATION

Hardware boss
everything is clear ralativement Despite the small size of the screen!

SOUND QUALITY

8 / 10 from the release date:
for prampli so his boss (the enctre MSOC), we like it or not! but it is possible to ring distortion uninhibited competition fae all lamps (diffrent, but ...!)

for effects against by saying anything, all right ... the reverb, delay, mod, pitch etc..

OVERALL OPINION

Good rack on the whole, with a versatile architecture robust and well finished!
for fans of the Boss pedals (all in one)!
