I have tube and SS. Practice is usually DI into the computer and out headphones. Most of the time with others I prefer using a Silverface Fender bassman head into 2x10. But sometimes reliability or convenience makes me use the old GK 400RB- that one used to be into 4x10 but now 2x10 (or I have a 1x15 I leave in the practice space and just move the head around). My best tone is the tube head and the Bassman into 2x10 sounds good for guitar also. But the tone from DI is pretty good with some computer tweaking and the GK is bulletproof and never sounds bad. I'm jealous of the workingman 10. Also somebody had a little ampeg that looked amazing. Lots of good stuff in this thread.
