When I bought this '81 AS200 it was outfitted with a non-original bridge. The original bridge was the ST style. However, as you can see from the photo, the posts are the thin threaded type, not the more common posts with anchors type. Because an original ST bridge with smaller diameter holes is so hard to find, I decided to try something I'd heard from another ICW member. I ordered a new 510BN bridge which is used on the newer JSM100 John Scofield signature model. The part number is: 2GB1G510G and the price is $85.00. As you can see, the bridge fits perfectly. I know that it's noticeably brighter than the tailpiece. Hopefully, someday I'll find a NOS ST bridge that will fit. But in the meantime, I think this will work and look just a little better.   Guitartim Username: Guitartim Registered: 4-2001 Posted on Monday, August 06, 2007 - 4:58 pm:    Nice work, Johns~ The JSM's 510BN bridge is a fantastic piece of functional art by Gotoh. I'm glad I'm not the only one who isn't afraid to improve a vintage piece...................with reversable mods.   Ibanezfreak1960 Username: Ibanezfreak1960 Registered: 3-2004 Posted on Tuesday, August 07, 2007 - 10:11 am:    John did you decide not to use the new thumb screws?   Johns Username: Johns Registered: 2-2001 Posted on Tuesday, August 07, 2007 - 10:26 am:    Freak: Yes, I'm still using the old posts. These things get screwed directly into the wood top and center block. I don't see that there would be any advantage to using the new ones. I really do have hopes of getting the "correct" bridge someday and then I'd have to pull the new posts back out.   Johns Username: Johns Registered: 2-2001 Posted on Tuesday, August 07, 2007 - 10:32 am:    Hey Tim: Question: do I have the bridge facing the correct direction? There would be no way to set the intonation if I spun it around. But having the beveled edge of the saddles facing forward isn't the norm for this Tune-o-matic style bridge, right? I'm getting paranoid.   Peterdryan Username: Peterdryan Registered: 6-2007 Posted on Tuesday, August 07, 2007 - 11:13 am:    John - I've had bridges with the saddles facing both directions in the same bridge because I've needed that little extra travel for set up. Purity must bow to practicality. - Pete   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Wednesday, August 08, 2007 - 8:51 am:    I think the Gotoh bridge GB2540-002 fits, and it's a lot cheaper than this Scoefield solution: $32.- http://earthshakingmusic.com/PARTS-GTR_HARDWARE.ht ml I have a few GTR by Gotoh tune-o-matic bridges (nickel), one on a rosewood jazz bridge still in the wrapping and one without the wood (installed on one of my '78 The Pauls). They were cheaper than new saddles. Kept the old parts in the case of course... Don't know if there is an inch vs cm difference. Take measurements and ASK before you order! Ginger   Johns Username: Johns Registered: 2-2001 Posted on Wednesday, August 08, 2007 - 3:25 pm:    Ginger: You may be right about the Gotoh bridge fitting. I'll check out the measurements. Here's another link where you can actually see the bridge and posts. And the cost is only $27.95! http://www.guitarnucleus.com/gnstore/brdg.html   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Thursday, August 09, 2007 - 7:23 am:    Allright! I just googled for Gotoh GTR tune-o-matic, because my bridge was sold under the GTR label. When I remove it from the rosewood base, it says "Gotoh" on the bottom. But the keyword GTR isn't in every parts ad of course. I saw a few dollars discount, and it seemed reasonable, but $27.95 is even better.

Take a look at my stock JSM's bridge:   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Friday, August 10, 2007 - 7:44 am:    Johns, the Allen heads should indeed be in a position where you can reach them, but the beveled side of the saddles should also be pointing downward at the tail. I think you should take the saddles out and put them in the other way around, like this: https://cs.hoshinogakki.co.jp/i-public/faces/Login 00.jsp Ginger   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Friday, August 10, 2007 - 7:49 am:    BTW, are the Allen on your guitar or Philips? They look a bit different... Ginger   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Friday, August 10, 2007 - 7:51 am:    Correction: the should be they   Johns Username: Johns Registered: 2-2001 Posted on Friday, August 10, 2007 - 7:21 pm:    Tim: Could you upload a closeup picture of your bridge? Thanks!   Guitartim Username: Guitartim Registered: 4-2001 Posted on Saturday, August 11, 2007 - 11:25 pm:    Johns~ Sorry, I've been on the road all week and no way to take close-ups at this time. BUT...here is the next best thing. How about a big Japan catalogue shot?   Gemberbier Username: Gemberbier Registered: 5-2006 Posted on Sunday, August 12, 2007 - 1:13 pm:    Johns, it looks like the JSM100 offers more space between the bridge and the pickup. There is enough space to use small Allen keys. But the saddles must be placed as I described. So in order to be able to adjust the saddles you should put them the other way around (IF POSSIBLE OF COURSE), because the AS200 offers too little space for adjustment between pickup and bridge.
