I was making an extra three-string removable pickup from my JSA Nd144 Electromagnetic Cigar Box Guitar Pickup and started thinking about some of its other features.

I recently found an old tube oscillator at the antique mall and thought I might be able to do something interesting with it. So I hooked up the removable pickup to my amp and powered on the oscillator. With one hand on the frequency knob and the other manipulating the volume via pickup proximity, you can get some pretty cool brassy synth tones.

The removable pickup is made of a 9v adapter coil and a homemade 1/4″ jack.

The wiring is simple—two terminals on the pickup: one attached to the hot on the jack and the other to the ground on the jack. Then, I just taped them together.

I need a bit more practice, but here is a quick and dirty video for now:
