I had the bridge worked on so that the strings would be lower on my chadwick. The bass plays like butter now but... the bridge is falling pretty frequently. I don't know if it is the shallower angle now or what, but the bridge gets pulled forward (forward as in towards the fingerboard/up) very easily. I've had this bass on tour before and have literally tore it down and set it back up hundreds of times (it's a chadwick folding bass). I never had this issue before the work was done on the bridge. I am very thorough about making sure the bridge is perpendicular when setting it up. When I check it after a few minutes of play I frequently catch it migrating. I am not ecstatic about cranking the string height back up to try and fix the issue. Not even positive it would. Any thoughts on what could be causing the problem and how to alleviate it? This issue has gotten bad enough that I am not taking it on gigs and taking the slab instead. No bueno. This bass is playing exactly the way I want it to right now. I'm of course not playing the way I want me to, but that's another issue. couple notes: I've graphited the bejeezus out of the slots. Several times. I don't think that is the issue. It is strung with helicore hybrids, mediums I believe. Not spiro starks, but not uber low tension guts either. I wouldn't think that the pressure holding the bridge down would be inadequate. It seems to be more a function of the top of the bridge moving. I realize they are probably related. I don't pull extremely hard when I play but I am not a weanie about it either. I never play without amplification and I try to let the amp do its job/only pull as loud as needed to get the tone I'm after. That being said, I am just as guilty of getting into it sometimes and pulling a little harder than needed as the next guy.
