Good question. I really debated with myself to do this mod, especially on my Custom Creation and rare made for NAMM Spalted ASAT.
The step bit is manufactured by Irwin United. It is their #4 bit. The maximum size on this one is 7/8, so it was perfect for our needs. It was in the $40 range. The blue area is just where the info about the bit is printed.
I measured the diameter from other basses (MM & Fender) to get the size. Being a step bit, I was able to enlarge the 3/8 existing hole in very small increments to the required 7/8. Removing small amounts of wood with a high tech bit kept the finish from being damaged. The 3/8 hole from the barrel jack acted as my pilot hole. I had to be careful about doing any damage to the wiring or preamp components in the cavity by visually watching as I drilled. I mounted the new switchcraft jack (three prong type) to a jack plate and drilled just deep enough to accommodate the new jack. After the new jack fit into the body, I marked where the mounting screws would be and drilled pilot holes, again not to do any damage to the finish.
I suppose I'll "fix" my other G&L's. Well, maybe not the Commemorative or the ASAT Signature. I believe the Signature to be the first ASAT Signature.
Thanks for "BassesbyLeo" We finally now have our own site to call home.
