      Conversion posts will not fit my chibson.
      posted Jul 14, 2014 by AdamLondon
      I bought a set of the conversion posts as I wanted to install an abr-1 on my chibson. Now after watching videos on line and making sure I had ordered the right posts. They are the wrong size completely for my guitar and can’t screw in at all. Shame as I have already ordered a bridge and now can’t fit it. Are the specs changing on some of the newer chibsons? I am not sure what to do now. The conversion posts are to large to fit in the holes in the guitar. Any idea guys I am stumped I can try to take some closer pics next time I take the bridge off.

      It’s probably the bushings that are the wrong size for those posts. Did the conversion kit you order include any sort of requirements (normally labeled like m6 or m8 posts)?

      I ordered these

      But on the bag. I see it has a code Bp-3041-nk maybe I have ordered the wrong thing.

      I think I found my answer

      **Please check the diameter of your original posts before ordering. The diameter of the threaded section of your bridge posts needs to measure 7.9mm for these to fit. The 7.9mm(M8) diameter bridge post are found on most Epiphone and the better quality import guitars. Some inexpensive guitars coming from China are using a smaller 6mm(M6) threaded bridge posts. This includes many of the fake Gibson guitars…we do not sell a conversion posts or a bridge that will fit these guitars.

      So I will have to find a metric bridge

      Well, I’d say it would be cheaper to find M8 bushings.

      Something like that, though Stewmac is normally really expensive. You don’t need the actual stud part that the stop tail latches onto, but the M8 threading inside is what you need for those conversion posts.

      Thanks guys. I have totally have become confused by it all.

      If I was to buy a Gotoh bridge with the following specs below. Do you know if it should just be able to pop right onto my chibson? I want to give up on the conversion thing. I just want to drop a new bridge on to the adjusters I already have on it. I will measure it tonight.

      I really am completely confused by all of this 🙁

      But I’ve ordered my pickups at least 🙂 Seymour Duncan SH-4 in the bridge and Seymour Alnico II Pro in the neck. can’t wait to try them out.

      Bridge post hole diameter – 6.5mm
      Centre to centre spacing between the two mounting post holes – 74mm
      Centre to centre of the two outer saddles (low E to high E) – 52mm

      Yes, that should drop right onto your current posts. I’ve installed Gotoh’s on three of my Chibsons so far (with a fourth on the way).

      As we always say around here though, measure your own as our experiences may differ.

      Take the bridge off your chibson and measure that thin part of the post that the bridge sits on (where it has the slat for a flathead screwdriver to fit int). That should be 6.5mm or less. If it’s less, that’s not necessarily a bad thing as with strings tuned up to pitch the bridge won’t be moving around at all anyway.

      Gotohs also come with their own studs/bushings most of the time (unless the seller skimps out on you and takes them out of the package). So in the worst case scenario you could install the new studs/bushings that come with the Gotoh.

      Here’s a nice video of a guy removing bushings from a Les Paul and making a little rig with a large screw and a very small piece of PVC pipe. https://www.youtube.com/watch?v=Q1ppKxEIF1M

      Alternatively, you can just get a really long screw (remember, you’ve got 6mm posts in the guitar already so you’d need an m6 screw) and screw it down into the guitar like this: https://www.youtube.com/watch?v=sQ5yM7Mj7MM Bushings are hollow, they don’t have a “bottom” so to speak so if it’s screwed in so far it will start to lift out of the wood.

      Again, with the Gotoh you should NOT need to do either of the above, but you’ll have the pars needed if you happen to need to do just that.

      Richard at Sinewavemusic is really great to deal with.
      If you order the bridge,then my advice will always be change all the components,including the bushes,as the components are designed to fit together.You might find the Gotoh bushes are very slightly smaller,this can be taken up by wrapping some PTFE tape around the splines on the bushes,but keep it below the top flange,failure to do so might result in the tape pushing upwards and stopping the bush to be seated correctly. You could also use Aluminium kitchen foil,or better still use copper shielding tape.
      Hope that helps

      Thanks for your help guys. In the end I’ve gone for the the gotoh bridge. To keep things simple. can’t wait for the bits to arrive. New bridge new wiring new pickups and new nut. The tuners will stay for now!

      Just got my Gotoh GE103B-T bridge in today for my PRS like guitar.

      It dropped right in onto the posts that were already in the guitar, but I wanted to use their posts/bushings since they were a slightly different color.

      I just took a long M6 screw and screwed it down into the Chinese provided posts, and it lifted right out of the guitar like those videos that I linked you above. Just slapped in the new bushings (didn’t need any filler to make them tight) and a light couple of taps with a rubber mallet and they were good to go. Took me about thirty seconds on each side, no joke.

      Hopefully yours goes just as smoothly as mine, Adam!

      AdamLondon said Jul 18, 2014
      That’s great. I receive mine today just put it on now. Just the original bushings and adjusters. Works. Treat and it’s snug fit. Haven’t set up the intontion yet. Gonna get my pickup wired tomorrow nod replace the nut.

      Thanks for your help again everybody.

      Also can’t wait to put these in!

      Great looking flame on your guitar by the way. 🙂

      The gotoh bridge ended up being so much better than the stock one for me. Took care of all my intonation issues.

      what are folks thinking about roller bridges?, I have a PRs style with string through design and abr1 style bridge,

      why do I remember someone saying these things have problems??

      the manufacturer keeps saying how great it works with trem or bigsby style,how’s it work with not that 🙂 its cool looking ,but im going for functionality ,I do a lot of bending so,,,,

      I am almost locked in to the gotoh GE103B,pulled Everything out of this guitar, studs bushings,etc,either the gotoh or the tone pro ( love the locking feature, not the price, I

      I know these subjects have been beaten to DEATH,yet,here I am,

      I’ve got an ABR-1 style roller bridge from Guitar Fetish on two of my guitars that I love.

      The gotoh is a home run on my PRS style guitar. Totally solved intonation issues I was having with it.

      MichaelWamback said Jul 20, 2014
      I think roller bridge can be beneficial on guitars with a trem. Anytime you can remove friction on those, it’s a good thing. I know that some people love them on non-trem guitars, but I’m just not one of them. For a non-trem guitar, give me a Gotoh or Tonepros Nashville bridge every time.

      I’m running 10’s on it right now but will probably swap to 11s once I get a new nut.

      Hope yours is as fun as mine has been.

      HtesJoseph said Jul 20, 2014
      so I popped the nut last night and put it back to back with the nut that came on my chibby,and its exactly the same,so I will be picking up another tusq xl,I went ahead and got that gotoh bridge and ordering some semour duncans now,and yes this thing has been a blast this far.

      how did the bushings fit back into it that came with the gotoh? I know that what came with my prs was the crappy tin foil bridge with the m6 threads,and the new ge10b has m8 threads. I took some mesurements and its all close,did you have to wrap any foil around the bushings?
      PS, I used your trick with the screw to get the bushings out

      I didn’t need to wrap any foil around them. They were nice and snug, I had to use a little rubber mallet to tap them in the last few millimeters or so.

      Check out the eBay seller called banjomikez http://stores.ebay.com/banjomikez

      He has some in custom colors you can’t get anywhere else and great prices. Got super fast shipping when I bought mine. I got white bobbins with gold pole pieces for a white Les Paul.

      Most people go for the SH4 in the bridge, that’s called the JB by Seymour. The SH2 Jazz in the neck. Like this

      http://m.ebay.com/itm?itemId=190855602633

      The sh 1 59 isn’t a bad neck pickup at all. All of these are basically a slightly newer age take on the older 50-60’s style pickups. The JB is basically a PAF on steroids as they say. Cleans up super nice.

      Edit: Also since I’ve got them in mine, honestly I love the new EMG 57/66 combo.

      They’re brand new designed to give the benefits of passives and actives rolled into one. Alnico V magnets, steel poles, etc while still giving completely noiseless operation. They’re not as hot as EMGs more metal minded pickups and have such great clean tones that I hardly touch my passive equipped guitars now. If you look into them check an eBay seller called donttellthewifeguitars he sells the sets in all finishes they make.

      That’s them. They are the set that put Seymour Duncan on the map of guitar enthusiasts. Also be sure to look up clean videos of the EMG 57/66 if you’re shopping around still.
