Hey, I want to install a piezo pickup under my Wishbass JB bridge. The bridge is walnut, handmade, the piezo will be one of those ultra-thin, tape-like pickups from Pickup the World, and I'll swap out the 'stock' KA MM-style mag pickup for a Häussel walnut-covered MM pickup. I was thinking of running the piezo through a John East treble/bass stack and the mag pickup through a John East mid/mid stack and then blending them through a BARTOLINI MPB2918 Magnetic And Piezo Buffer/PreAmp w/25 Trim Pot. That would then go through a volume pot before exiting through an output jack. Any thoughts? I'm a total newbie when it comes to this stuff, so don't hesitate to talk down to me, I won't be offended.
