I was thinking about doing this but then I thought I might butcher the pickgaurd and end up with a flawed template...Blueline said:without sounding like a jerk, here's what i'd recommend doing
if you have a router/table which i assume you do since you asked for the template
1) buy pickguard in desired shape
2) rough cut template material of your choice - i alwasy like plexi, but some people like mdf or steel
3) double sided tape rough cut to real pickguard, router away
hope that helps
