Well, this is out of my hands now, all the parts are in and The Kingfisher is in the shop. They have worked with these before on larger guitars with easier access, this installation may be a challenge due to the smaller size and smaller f-holes, so everything will have to fit through the bridge pickup route and into the hollow wings. The LR Baggs Control-X pot has a little circuit board attached to it, so it might be a challenge to thread that in place through the existing wire way. This job may take them a while, I will post updates. Of course all the wiring instructions from LR Baggs for their piezo system are oriented towards Fender or Gibson wiring, not exactly applicable to Gretsch, but I think they can figure it out. Here is my concept of how the final controls will be incorporated. Not sure if there will be any major obstacles, some of the components are pre-wired and would fit fine in a single control pocket, but I want to relocate their mini-toggle in place of the original pickup selector switch, which will be replaced with a pickup Alpha MN Taper Panner/Blend type of pot. Both the Neck and Bridge volumes will be replaced with blend pots, one for the Piezo/Mag blend and the other with the Mag Neck/Bridge blend pot. Crazy enough, it just might work! Why? Well, I always wanted a piezo in one of my electrics, and this just seems like the right one suited for the job. And I was really inspired to act on this now by another NGD post (a really awesome PRS SE Piezo) by @LivingMyDream, so rather than living vicariously through his dream, I am making my dream a reality!
