Boss PSA120 A/C Adapter For Cmpct/Twin Pedals
ROLAND/BOSS 9V POWER SUPPLY Why not use a power supply instead of hoping that 9 volt battery will hold up? The PSA-120 can be the power you need instead of a battery. It’s the recommended power adapter for products requring a 9 volt power supply - including many BOSS compact pedals, the DB-66/88 metronomes, DR-Series drum machines, FC-Series foot controllers, MC-202, SH-101, SP-202, TR-626, and all TU-Series tuners.
