I've put together an Ash bodied Warmoth Parts-O-Caster with a Fender American 2 post trem. Currently the trem is full floating and the guitar lacks sustain. It also is kind of dead sounding acoustically. I'm considering installing a wood trem block or maybe one of these new aftermarket trem devices like the Tremel-no I'm wondering how much this will actually improve the sustain on the guitar? Will a wood block improve the sustain? If so by how much?
