I bought this from another bass chat'er Protium last year who builds these incredibly impressive units at home and decorates each type with a distinctive image.
It's a wild fuzz pedal, comparative to Z-Vex's Wooly Mammoth but at a fraction of the cost. It features a red LED indicator when the effect is engaged, and I find it performs best with passive basses.
It came to me battery-only, but I've since had it professionally customised to accommodate a 9V power supply jack.
I also had the top of the pedal coated in lacquer to protect the Love Heart logo.
Home use only.
