The tone control looks 60's to me, too...and thanks for the advice. I will definitely be trying out this method. If you look at the 2nd picture I posted of the butt plate, it sure looks like that is the overlay of wrap...but as you mentioned, I should be able to tell as soon as I take off a head.Snare should be here on Thursday and then investigation will begin!
Sounds like fun...let us know what you find!
