Nicolas, from France.
I tried to put my new m1a on my Guild M20 ( http://www.guildguitars.com/index.ph...view/GAD-M201/ ) , and ... impossible, the sound-hole seem to be too small for this pickup. I can read in the manual that 3,5" is the minimum, mine is 3,58 (center).
Is there a method for small sound-holes?
Do i have to enlarge a little ?
If someone had the same experience with a small body guitar ?!
