This is the stock preamp out of a Steinberger Synapse. It's a model "0070-0083 A122 V2 SYN-B" (that's what's printed on it, at least). Here's the PDF wiring diagram
It works just fine. 2 band, boost and cut, has trim pots for pickup balancing and total output.
Includes the ends of the quick connects and the jack.
Includes the knobs as well.
25k volume pot, so designed for active pickups
This isn't going to drop into anything easily. Most likely, if you aren't using a Synapse, it's going to be kind of hard to make it work without some effort. But wiring guides are available on the interweb. $25 shipped to the US.
Paypal or MO. Int'l okay, but I have to get a price quote.
PM if interested.
