Tone Generator

A simple tone generator for pumping signal into your circuits when testing. Keeps your hands free and your precariously knee-balanced guitar from crashing to the floor.

We've designed it as a self-contained unit without an enclosure, as there's not a lot to damage on there as it sits on your bench. You can opt to put it into an enclosure if you prefer. 1590B will take a battery, 1590A won't. Your other option is to have a trimmer for a fixed volume output or leave it as a pot - the latter makes total sense.

Inspired by: JMK tiny tester
