Barcus Berry 3000A Buffer Preamp EQVerified

From the post

I know, I know. Another day another layout from me. I mean Jez, can't I let one of the other guys post a new layout for once this month? You guys must be sick of seeing my name pop up with a new layout... Anyways, this time I decided to do something different the the massive amounts of fuzzes I've been doing.

I've seen a few posts in the requests over the years for people looking for a preamp for Piezo pickups. The Barcus Berry 3000A is designed to work for acoustic piezo pickups but is also a buffer, preamp, and EQ. This is the only info that I could find on it:

The Barcus Berry 3000AE Piezo Buffer Preamp with EQ is specifically designed to work with all Barcus-Berry electret microphone systems. Features external bass, treble and volume frequency controls to allow a wide range of adjustment. Includes a belt clip for unrestricted movement.

Barcus Berry 3000AE Piezo Buffer Preamp Features:

• Features external bass, treble and volume frequency controls for a wide range of adjustment.

From what I see from the schematic I have no question that it will work with any Piezo pickup, as there doesn't seem to be anything really special to tell me it can only work with theirs. Mostly it's just marketing to get you to buy their pickup.
