and let me know what you think. The cavity will be about 1 1/2" deep, plus a smidge depending on how the pots fit. However, I was planning on making the battery area a step up, so it would be just over 3/4" deep. The reason for this is that area will run slightly under the bridge, and I want to leave plenty of wood for the bridge screws to dig into (I could shorten the screws, but would rather not). So, there will be room for the batteries to lay secured in their clips and there'll still be room left over to seat the cavity cover flush with the body back. I did not draw in the routed lip area that the cover will rest on or the wood where the cover screws will dig in. The spots where the horizontal lines are intersected with vertical lines are where pots holes will be drilled. From left to right on the upper line: a/p switch, bridge vol., master tone; next line is neck vol. and stacked treb/bass, and the final line has the sweeping mid. The small square to the right is the room for the jack, though it may well seat further into the wood. I did not include the spot for the Aguilar pre, but I've measured a few spots, and have a few usable areas for it. If you would, please give your thoughts on what will or will not work (in your mind). If I get the thumbs up from enough people here, I'll secure this to template material and start cutting templates. Thanks!
