Well - i have tried it. I personally do not like the new synthetic distortions that sound so extremely sharp. I prefer my good old Digitech RP7 and my ART SGX2000 - both use a combination of tube and transistor and they produce the tone that i want. the cool thing is, that the boss offers tonns of effects - useful and useless ones - however - for the price you get a pretty cool effectsboard with the gt6 - not my taste though.
