I bought one of these a few months back and think it is the coolest amp for practice and small gigs! It looks cool and sounds FANTASTIC, esp with passive basses I use. I disconnect the tweater and get an amazing, warm vintage tone. I have read on another site some folks are getting these that don't work, but mine works just fine, bought it brand new. Right now I am playing a Waterstone Indra I bass, short scale, through this combo, and it sounds huge, round, and BASS-Y. No pedals, no effects, just straight into the Ampeg. Anyone else out there using one of these? Your thoughts?
