louisthebass Posted October 28, 2011 Share Posted October 28, 2011 (edited) Hi all, Wonder if anyone who owns a Yamaha TRB bass with humbuckers has had a similar problem to mine? I keep having to adjust the height of the rear pickup as the top of the pickup is getting too close to the strings - I'm not sure if it's an issue with the sponge underneath, or if one of the screw holes needs filling and retapping? If anyone can help, would be very much appreciated Cheers, louisthebass Edited October 28, 2011 by louisthebass Quote Link to comment Share on other sites More sharing options...
nugget Posted October 28, 2011 Share Posted October 28, 2011 Hi - not experience that before, but if the pickup keeps getting higher then the screws must be coming undone, most likely the vibration making them unwind. I would try and fill the screw holes to make the screws tighter. Good luck Quote Link to comment Share on other sites More sharing options...

steve-bbb Posted October 28, 2011 Share Posted October 28, 2011 do you (like me) use the top edge of the pickup cover as a thumbrest? Quote Link to comment Share on other sites More sharing options...

Do you think this could be part of the problem? [/quote] well if youre heavy handed like i am then the weight of your thumb/hand combined with the slight rocking motion against the pickup is going to pull against the screw maybe - youre basically pulling against the strings so there will be an approximately equal opposite force going through the pickup/body where the tip of your thumb connects with it and unless you play with your hand absolutley still then there is going to be 'some' leverage against those screws maybe a combination of that and what nugget says above - sounds like you might need to plug the screw holes with some slithers of wood to pack the screw in tighter Quote Link to comment Share on other sites More sharing options...
Burg Posted November 27, 2011 Share Posted November 27, 2011 I had a similar problem with the front pickup on my TRB-II 6 string. The screw kept coming loose. I stuck a bit of matchstick down there and that gave something for the screw to grip on to and it's been fine since. Quote Link to comment Share on other sites More sharing options...
