I can't seem to find any information on this. But I would like to change the string gauge on my Guild GAD 40 to 11's or 10's. I'm not sure, but I think it might have came with 12's on it. I want to change to a lower gauge so I can add some vibrato easier and do some small bends, cause I play mostly bluesy stuff on it. I'm assuming I'd have to adjust the truss rod, is that all though?
i doubt you'd have to adjust the truss rod if moving to 11's, but you probably would for 10's. before doing anything, see if the guitar buzzes. if so, adjust - if not, don't. btw, we have 10's on a bunch of our guitars, and didn't have to do anything beside a minor truss rod adjust.
