I'm in doubt between the Bugera G5 and the G20 Infinium. I need an amp to practice at home, so the G5 is very suitable for this purpose. I think that the G20 could be good option to play at home and it has enough power to play at small studios or gigs. But I'm afraid of disturbing neighboors when trying to distort sound. The master volume of G20 act similarly as the power attenuator of G5? Could I get a nice tube distortion with a low master volume? Thank you.
