Note : No original power supply. I've used a one spot adaptor and it works perfectly. Any DC 9v volt power supply like the one spot will work no problem as that's what i have used.

Pedal Aficionados welcome. You're in for a rare treat. I wish didn't have to sell this. And i may change my mind if my situation changes, but recent financial problems has forced me to sell this order to keep my car and maintain my life. The Yamaha SB-40 is a incredibly well built and amazingly cool  multi effects unit!! All the units are awesome but the Flanger is legendary. It's just pure liquid color!!! I had this especially brought over from Europe when i found it many years ago. The effects are all analog : flanger, distortion, octaver, and chrous. You can change the order and you can also run the pedals with out the mother pedal board holder.I'm asking a fair price as this is the only one around. and it will appreciate as time goes by. International buyer contact me first as i may get better rates for you. If my financial situation changes don't be surprised when i take this off the market. cheers and thank you for reading. radio.........><<><><>
