Fulltone True-Path ABY Early Aluminum Version

This is an early Fulltone ABY pedal with the original box #50 signed by Mike Fuller. Rare. These early pedals were made with bare aluminum housings and decals for lettering . Back "in the day" around 1991 Mike Fuller won the best amateur guitarist award from Guitar Player Magazine . He won because of his really incredible tone and that was because he hand-made his own effects pedals . Well after that everyone wanted one so he started up Fulltone and these were the first pedals that he made . This pedal works great with no issues (some folks collect these early versions) Btw at the time this idea of using photocell tech was a brand new idea . Optocoupler Switching: Rather than running the audio signal directly through mechanical switches, it uses advanced photocell technology (opto-isolators) to route the signal, preventing switching pops or "thumps".
