This is a vintage, handmade TS-style pedal from RCS, a musical instrument store in Kyoto. I purchased it new about three years ago and used it for a long time, but I'm selling it to organize my equipment. The explanation I received at the time of purchase was: * The gain is set higher than a typical TS-style pedal, with the gain at 12 o'clock being equivalent to the maximum gain of a typical TS-style pedal. * It is the most standard model in RCS's TS-style pedal lineup. Operation has been confirmed with an AC adapter. There are some paint chips due to dents on the exterior. Please feel free to ask any questions you may have. Thank you.
