I have a peavey AC BXP 5 string with the individual bridges for every string. My intonation has always been out of whack. No matter how close or how far I've moved the saddles, nothing works. I have also tried many different guages, which helps, but has not fully corrected the problem. So, my question is could i buy a 5-string fender style (string-thru) bridge on ebay and be able to install it easily? Thanks.
It sounds like you have no idea what you are doing when you are trying to intonate? The correct intonation will never be at the extremes of the bridge. Look up the ultimate setup thread.
