I've got an early to mid 80's Peavey Foundation 4-string that I picked up a little over a week ago used. It played amazingly well for the first week. Now that I put new strings on it and played it through a gig it seems to have developed a bit of a neck warp on the G string side of the board. No matter what I do, I can't seem to get the warp out of it. I left it at my local shop (that I trust very much) to see if they can iron out the problem, but I'm not very optimistic. Now, it dawned on me that I've got a Warmoth 4-string neck just sitting here that's not being used for anything. I've seen a Foundation with a Moses Graphite neck on it, so that makes me wonder if a Warmoth replacement would fit just the same. Does anybody know how closely this bass will conform to Fender heel specs?
