I finally got an all tube amp... But it's a guitar amp. It's pretty sweet sounding. 30 tube watts into a single 12. I will use it to record all my new tuneage. It has: 2 12ax7s for the preamp section 4 6bq5/el84 with 12ax7 driver for the poweramp section. I don't know what all that means be it sounds better than my previous practice amp, it is pretty light for a tube amp, it has a vintage vibe... I am way stoked about it!
