I can't remember the thread, but someone asked about a neck radius guage. The Pickguardian site (just scroll down) has some guages you can print for free and cut out. They work just fine. BTW: I don't have anything to do with Pickguardian other than I was a customer once. To highjack my own thread, I've seen some threads about basses with "NBD" in the title. I thought this meant No Big Deal but it doesn't seem to apply. ???
