My M2500 Tribute, purchased new, is beautiful, sounds awesome, and about every 1 - 2 weeks needs to adjustment to raise the bridge saddles and stop strings buzzing on frets.
This is my 1st G&L instrument and my first experience with the saddle lock bridge so I may be doing something wrong or leaving out a step in the adjustment process.
Here’s what’s happening, I can go through setting truss rod, saddle height, intonation, and then finish by tightening the saddle lock screw. I’ll play it for a week or two then the next time I pick it up to play I notice strings buzzing on frets. Initially I thought the neck wasn’t holding adjustment. Ultimately each time I discovered the bridge saddle screws had loosened and some saddles dropped to their minimum height, some adjustment screws turned freely and not in contact with the bridge plate.
Yesterday morning I picked up the bass to play and there was the dreaded string buzz again! This time I put the hex key into the saddle adjustment screws before loosening the saddle lock screw or checking anything else and darned if several of the screws could turn freely, no contact with bridge plate. I reset the string height, tightened the saddle lock screw, and then checked the saddle height adjustment screws, several were loose.
This leads me to believe that possibly the bridge is flexing slightly when I tighten the saddle lock screw, raising the saddles slightly, and relieving tension on the saddle height screws allowing them to vibrate loose as the instrument is played. Interesting that I only notice string buzz when I pick up the instrument to play the first time of the day but perhaps I don’t notice strings playing cleanly then buzzing in a band setting? That said, my final setup step yesterday was to snug each of the saddle height screws (after the saddle lock screw was tightened) to make sure they had some slight torque.
Has anyone else experienced this? Any ideas on what may be done while performing a setup that I haven’t done to hold string height adjustment? Perhaps a neck shim so the saddle height screws extend further from minimum adjustment height? Thanks
