1967. Recentlly cleaned and serviced. One of the MP1's channel is an instrument input with volume, treble, bas, and reverb controls, while the other is a microphone input with volume and tone controls. The tremolo uses an LDR (like a Ampeg Gemini I) to limit the instrument signal post preamp. The reverb uses a 12AU7A as phase inverter for a 25KCT:8ohm reverb transformer (This was an interesting step for engineering, all the previous Estey reverb circuits used a tube stage as a driver). $399 CDN
