Tremolo pedal used in WINO's masterpiece 1st album "Useless Music," which has been re-formed, for the song "Confusion" because "it swayed more violently than the tremolo of a Vox amp." Personally, I think it's a masterpiece, with a comfortable, analog-like sway that has a solid center of gravity, more so than the Strymon FLINT. This is the early model with two circuit boards (the reissue version has one circuit board). You can adjust the speed with an expression pedal, and you can also set it to half speed with the footswitch. By raising the output and turning off the tremolo, it can also be used as a booster. There is some paint剥がれ (paint chipping) on the right side, but it's generally in good condition. Operation has been confirmed. Can be powered by a 9V battery. The serial number has been masked for security. ＜Included Items＞ ・Box ・Instruction manual
