I've been working on a (Fender) Squire Mustang bass, you can find them online at MOST of the Fender retailers. These seem to be ideal for modifying since you need to clean up the neck anyway. Comes stock with the "P-type" Mustang PUP. The true Mustang's are hard to find USED at a reasonable price and in the original PUP configuration. Everyone I've seen is listed as a "vintage" instrument or it has the "newer" P/J PUP configuration. The Squire series is the closest I was able to find that was priced low enough to justify modifying it as an amateur tech/woodworker.I will post pictures when I get closed to finished.
