I think you may have meant to ask me that question, my friend (unless gsgbass is planning the same swap out). I'm still waiting on the work to be completed. The pup needs a slightly wider route than the stock pup. I talked to the luthier yesterday, and he said that it's going to be about another week to get everything routed and swapped in. As long as the work is done right, I'm ok with the wait, but I am missing my little SG! I bought a used Lakland Skyline DJ4 to get me thru the wait, though! The shop I'm using has a good reputation, great service, and it's where I bought the bass last month, so I'm not worried, and mine isn't the only instrument being worked on. The total for the routing and install is going to be $80, not bad, especially considering I wouldn't be able to do it myself!
EDIT: Those Lavaburst pics never get old, btw, and your new Supreme Maple is beautiful, even with the minor issues you described.
