Just finished converting my old US Std to Brent Mason configuration with a SD Vintage Stack in the bridge. However... found out the Vintage Stack is a little taller than a regular one, and I can't get it low enough to dial in. So, either change out the pickup or deepen the cavity by about 3/16 - 1/4". However, I don't have a router to do this. Short of taking this to a local shop and waiting weeks get it done (and this is my main gigging tele), is there a simple DIY way to do this...like, with a drill/rotary tool, a router/cutter/forstner bit, and some sort of guide to keep depth uniform?
