Orange/Apollo™ Tone Boosters

This is a replica of the Orange or Apollo Tone Booster.  This booster uses a germanium transistor (also sound good with silicon transistor) and comes in a couple different configurations.  The original didn’t have a volume control, but we recommend adding a Volume Control.
