Jaguar/Jazzmaster ATOM bridge defect.

Post by Jimir » Sun Jan 19, 2020 5:10 am

Hi guys
A number of months ago I bought my first offset, a Vintera Modified Jazzmaster. In a previous post I mentioned the problems I encountered with the Adjustomatic bridge on this guitar as in loose saddles and a rattling circlip. This problem was encountered on the initial Jazzmaster bought, a replacement bridge sent by Fender and then the new guitar that replaced the original Jazzmaster (Mastery Bridge was eventually fitted.)

Recently I had the opportunity to buy a secondhand Classic Player Special Jaguar in virtually mint condition for a very good price. When I viewed the guitar I noticed that it had the exact same ATOM bridge as originally fitted to Jazzmaster so I was careful to check that it didn’t have the same problems. It didn’t appear to however the saddles had never been adjusted for intonation and where in a straight line near the front of the bridge.

When I got the chance to set the guitar up and properly adjust the intonation I was very careful and made sure the string on the saddle was loose and away from the saddle when I adjusted it however as soon as the saddle on the B was moved backwards guess what, the exact same problem appeared as in loose saddle and rattling circlip. (I inserted a small piece of foam on either side of the saddle screw to stop the clip rattling and will probably fit another Mastery in the near future.)

This makes a total of four identical ATOM bridges where this defect has appeared. It’s caused by a thin, weak poorly manufactured circlip and on each occasion the problem has occurred on the B or G string saddle.

If you are thinking of buying any Fender offset with the ATOM bridge check the bridge thoroughly,
after four bridges I think I can confidently say that this is a manufacturing defect.
(The part code on the bottom of the bridge was the same on all four bridges.)

The CP jag and Vintera 60s modified JM do indeed appear to have the same AOM bridge. They have different Fender part numbers (0076230049 , 007623000) but Riley says those two numbers are the same part (Korean part number LPB-002 underneath) ..

A drop of blue Loctite on the circlip might be the best fix.
