Hey all - I have a 2010 Les Paul Standard that was gifted to me by my brother several years ago. I've been gigging with it a lot lately and finally settled on a set of pickups that really matches the tone I'm going after. I have CTS 500k pots and Lollartrons in the guitar, and added a bigsby with a vibramate. But I've noticed that even though I replaced the pots/caps and pickups, the guitar still gets really harsh high-end and ice pick effects when playing higher notes up the neck. Now... before throwing up suggestions, please kindly keep these things in mind: 1. I've run this guitar through several amps. It is not the amp that's the issue. 2. I've tried dozens of pickups on the guitar. This is not a pickup issue. The only pickups that didn't have this effect was with Lollar Imperials, which were great, but I settled with Lollartrons - they get extra sparkle without compromising thick low-end I want in a Les Paul (great pickups btw... I highly recommend these). I've been reading up and researching steel or aluminum bridge replacements. I'm considering going with a steel Callaham bridge. Even though steel is supposed to be brighter, I've read that it reduces the unpleasant highs. Has anyone experienced similar issues? It's this unpleasant high-end ringing that comes out when playing high notes. You almost hear the ringing more than the guitar.
