One-of-a-kind circuit bent General Electric (GE) vintage walkman style tape player featuring: bidirectional speed/pitch control knob, bidirectional drone knob, and 1/4" output. Runs on 2xAA batteries.
Super clean practically pristine General Electric (GE) vintage tape player. I found this device in practically perfect condition save for some corrosion on the terminals. I cleaned it up and modded it out. The mods are very natural looking and sleek.
