Vintage Peavey Mace with two JBL K120s for $400. It has a surprisingly good tone despite the solid state preamp section - channel 1 has the soul of a Twin Reverb, and channel 2 cops a nice Marshall crunch when you lean on it. It's also unbelievably frickin' loud (six 6L6CG power tubes, although one of the power tubes is bad).
I was only looking for spare speakers, and now I have (another) spare amp. I was going to keep the speakers and sell it the amp, but it sounds so good I think I'm going to keep it; it's an embarrassment of riches. For a guy who doesn't even gig, I have waaaaaaaay too much gear...
Dilettante - sounds nicer than "hack"
