I found an old R.A. Gresco The Force pre-amp and would love to put it to use but can't figure out how to wire this thing (see picture). I think that the brown wire might go to output but what about the other three and how to combine them? I know these are seriously rare 80s gadgets and not very well known but they were used by quite a lot of players, SRV and Nile Rodgers to mention a few. I also have a Tone Qube from the same company and it is a very nice addition to any guitar.
If anyone know anything about The Force and how to wire it I would be most greatful. But any hints are of course very much appreciated. Thanks!

it's hard to tell from a picture of a gooped board. could possibly be inferred from the trace side of the board (if it is not gooped). if not you might have to look into removing the goop (i'd look on the freestompbox/diystompbox forums for suggestions)

The fact that it's a "seriously rare 80's gadget" doesn't change the fact that it's almost certainly a very conventional FET or bipolar transistor pre-amp using a circuit you'll find elsewhere on this forum. The 80's were not a time of far higher sophistication or technical mastery than today, far from it. One of the main reasons a manufacturer bothers encapsulating a circuit in resin is to hide the fact that it's really something completely unoriginal that anybody with a soldering iron can design and build for a tenth of their retail price.
Come on Kit, you're such a cynic!
