I finally finished the speaker/amp thingy I mentioned some time ago. I fixed up a broken belt Marshal amp things, gutted it, hooked up some salvaged speakers from a broken Yamaha keyboard (that I fried hehehe) and built a case around it. The back is open so I can stuff in a proper surge protector that powers the amp and both cases above it.
The amp has some nice distortion and can quickly warm up or blast a sound.
