i have this preamp to put into the 5 string fretless i made last year:
At the moment i only have a single MM style humbucker so the balance pot will just work as a second volume. Fair enough, but i was wondering if it is possible to wire up a piezo pickup into that second input. The bass has an unused cavity under the forearm contour which i figure would work well for a piezo pickup / a nice deep, thumpy sound.
Does a piezo need any extra preamp stage or buffer or would it work straight into the preamp.
I'd also like to clarify the use of the gnd connection.... i don't have any shielding (future job) and my jack connector doesn't have 3 terminals like in the diagram, should i connect it to the bridge ground?
cheers.
