This is the BOSS dual foot switch "FS-6". After purchase, I didn't have much opportunity to use it and stored it in its box, so it is in 【very good condition】 with no noticeable scratches or dirt. It has two switches (A/B) integrated, and each can be switched individually between "latch" (ON/OFF each time pressed) and "momentary" (ON only while pressed). It also has a polarity switch, making it a versatile foot switch that can be used with not only BOSS/Roland products but also equipment from various manufacturers. 【Example Uses】 ・Guitar amp channel switching ・Multi-effects unit bank switching, assign functions ・Rhythm machine start/stop ・Keyboard control 【Product Details】 Manufacturer: BOSS Model Number: FS-6 (Dual Foot Switch) Power: 9V dry cell battery (006P) x 1 *Batteries are required for operation.
