Base pedal: BOSS® SG-1 Slow Gear
Compared to the BOSS SG-1 Slow Gear, a quirky 1979 pedal that automatically swells each note from silence — producing that lush, violin-like attack without needing a volume pedal. The original is discontinued and collectible; building this clone is the most affordable way to add hands-free auto-swell to your rig.
