An awesome vintage amp!

I used it at my local guitar shop and the tone was amazing when i ran a Squier CV 60's Strat through it. Definitely a bright amp, so i don't know how it'd sound with Distortions/Fuzzes, but the clean sounds and the amp gain/speaker breakup at loud volumes sounds great. It has reverb and tremolo. I'm pretty sure it Uses one 12 inch speaker for the dry signal, and an 8 inch speaker dedicated to the reverb.

I'm definitly planning on buying it.
