I'm looking for an installation manual and/or schematics for an early version of the Fernandes Sustainer circuit. I bought a guitar from the early 90s, the Sustainer works, but the wiring is a complete mess and the lever switch is broken. The circuit has only two trimpots and no coil on the pcb. The driver pickup isn't rounded like the new version, yet. Must be a very early version of the 401 circuit.
