Here's little studio amp I made over the winter from stuff lying around.

The cabinet is genuine plywood stained and cleared. The alnico 6" speaker, grill cloth, and power cord from an old tube record player I got at a junk store. The chassis is brushed brass with a clear coat, power transformer from an old boombox.

This is built with a hybrid 12V space charge tube amp circuit I made years ago with a new PCB PLUS a fuzz on another PCB I made.
Controls are: Fuzz Bypass, Shape, Fuzz, Fuzz Volume, Tone, Preamp Gain

The shape control is a rotary switch that selects input ("top") and output ("bottom:) caps. There are four settings:
Paris = thin top, thin bottom
Rachel = thin top big bottom
Pamela = big top, little bottom
Oprah = big top, big bottom
You can get ALL kinds of sound out of this little thing. It's never really clean, even with the fuzz off and the gain rolled back - probably the speaker. You can have real synthy fun with the neck pickup & tone rolled all the way back into Oprah or get the icepick through the forehead on Paris and a single coil. I've never plugged it into a cabinet but it should do pretty ok...
