Working on a Frankenbass project - a P-style bass: nice Warmoth high grade birdseye maple neck, black ebony fretless finger board, to a Lotus body, quite heavy and, I imagine, made of multi-layer laminate (plywood). It's a 4-bolt (screw) neck joint. The question is with the new neck plate, it came with a plastic gasket, said to give a more snug, tighter fit, as well as protect the body against being marred from the steel plate over time. The original plate on the Lotus bass has no gasket, so the body is already a little marred (clear impression of plate in the paint), so that not being a issue to avoid, I see I have an option - to gasket or not to gasket. I've read elsewhere where some argue that the gaskets may or not have a negative effect on tone and/or sustain, due to resonant energy being impeded by the gasket at the body/neck joint. Any truth to this? Is it that noticeable? How could the gasket impede sustain, since the acoustic coupling is nearly 100% happening in the body/neck wood-to-wood connection in the neck socket. isn't it? Has anyone noticed any real A/B difference with this, say between Fenders issued with and without the gasket?
