Default Adding additional bridge plate material for Trance Amulet install

Hey all,

I recently got a ‘52 J45 that has been poorly refinished in black with other various flaws so I’m not concerned about resale, mostly. I purchased a Trance system to install and realized the bridg plate just doesn’t extend far enough toward the sound hole to accommodate the transducers directly under the saddle line. A local luthiervi asked suggested instead of replacing the plate for a bigger one, he could simply clean up the glue spill out along the leading edge and add more material to create a larger surface for the transducer. Is this common? I’d have to imagine it shouldn’t be too much of a sound issue to have the sensor straddling a hopefully tight seem in the two pieces of plate material. Is this a viable option?

For your viewing pleasure:

First reaction, I wouldnít consider it myself, not wanting to mess with the original plate. I would clean up that glue line though, that looks atrocious.

On the other hand, why not give it a try? Your luthier could attach the extension with hide glue (removable) and if it doesnít work, just remove it.

I had a similar issue with a small bridge plate on an old D-18. The Trance is a good pickup, but I couldnít make it work on that guitar, not enough room. I tried in front of the pins (on the saddle line) and behind the pins too. The plate was just wrong for the pickup, not seating properly, both positions way too trebly and not normal, so I gave up.

Since then though Iíve had great success on that plate with a PUTW 54 mounted in the flying V position on either side of the saddle line (narrow end of the V at the front). (This is the alternate PUTW mount position, the normal position being on the saddle line like the others.)
If I had known this at the time, I would have tried it with the Trance. I bet it would work well.

The PUTW is awesome in that position, so Iím a happy camper anyway.

Hide glue is probably what we'd use for the plate extension. I think I'm over complicating the physics of a bridgeplate in how it translates vibrations from the strings to the pickups. A glued on piece would be no different than a larger bridgeplate that just so happened to have a hairlilne crack in the same spot as the new seam would be and I can't imagine a bridgeplate directly under a bridge resonates in any special way that the pickup would care about. Then again, I'm no audio physicist. I might go ahead with the extension hide glued in and see what happens.

Thanks for the perspective and suggestion of that PUTW system. I'll look into that as well. Somehow I missed that product when I was researching...
