I'm planning on doing something much, if not exactly, like this. Specifically, I've got a Mighty Mite Jazz body
stuck in Backorder Limbo
on it's way which I plan on turning into a P/J configuration. ('cuz I dig 'em!) To do this, I'll be using a pickguard from a genuine Fender Blacktop Jazz
bass as the guide. This way I don't have to spend a lot of extra time and money doing all the measuring/lining-up, making a template, sending it off and hoping it's a perfect fit. I can hand both the bass and the guard off to my local guitar tech so he can use it to re-route a space for a Precision pickup. Violá! No fuss…no muss!!
