I would put the wood wedge in there and then trim the cork to fit and be done. I farted around for years with not great fits and Mcgiverd solutions, and when I finally had my luthier put it in right I stopped having trouble. I put my StatB back in in the past few days and I am really digging it (especially with the Tonedexter) I have gone thru the vintage two element model and I think the single version is better (on the E side on some basses...some other basses have weird unevenness that is projected thru the pickup)
