GT-500

The GT-500 combines Fulltone's Distortion Pro circuit and an independent clean boost in one enclosure, each usable on its own footswitch or stacked together for more saturated lead tones. The distortion side delivers Fulltone's characteristic high-gain saturation — cascaded stages with the same voicing that runs through much of Mike Fuller's dirt lineup. The boost side provides clean gain for pushing amps harder or kicking solos above the mix. Stack them for heavier layered tone, or use each independently. 9-18V DC (18V for additional headroom), 14mA. Discontinued when Mike Fuller wound down Fulltone's pedal operations, but remains a sought-after used-market item for players chasing Fulltone's distinctive high-gain voicing.
