Evans used to make quite a few custom configurations but none of mine had a pot on the back. Are you sure it's not the fuse holder?

The Pot on the back of my '94 Evans FET 500 adjusts the pre-amp output, if you plug into the Pre-amp output jack, right next to it. I sometimes use it when I want to furnish a dry signal to the P/A system, to be mixed back into the stage monitors, so everyone in the band can hear me.

As a matter of fact, I just took my Evans Amp to Ed Buffington, in McLeansville, NC, last month for a going over, and sort of a "tune up". He changed out a resistor in the Pre-amp circuit to give more output for that purpose. He called it an update, since I had not had it back for anything since I bought it in 1994, when Darrell Stephens still owned the Evans Company. He also added a Thermyster as part of the update too. Hope this helps answer your question.

Thanks guys. The amp was purschased new last year and the pre amp outlet is on tne back of the amp. Does anyone know the amount of power the signal pre amp out is? Again thanks.

The pre-amp output on the back has very little output. It will drive a sound board and also drives my Tascam Cassette recorder.

On my FET 500, it's about 1.0 volt wide open, enough to drive most pre-amps. The power from this signal, will come from the power stage of what ever type Amplifier you choose to input to.
