Yamaha SB-40 Professional System Board in good working condition. Very rare interchangeable multi effects system made in Japan in the early 80s. This has some really good analog effects built in. Can be powered by standard 9v adapter (not included)
The new Yamaha PSE, 'Professional System Effectors', range provides the musician with a very versatile signal processing system. The range includes ten effect units, a 'mini-pedal', noise gate, line selector and two flight cases with integral power supplies and patching options.
Each pedal is housed in a smart black diecast box with a large rubber pad covering the base to prevent the pedal slipping under pressure. The supply, provided by a standard PP3 battery, is connected when a jack is inserted into the input socket.
Effect 'on' is indicated by an illuminated LED situated above the input socket. The footswitch, which has been custom designed for the range, inspires confidence in operation as do the controls which are smooth, well positioned with clear legends
