    I've been toying with the idea of an 8 string custom build and was wondering if anybody made an 8 string tune-o-matic, possibly with stopbar tailpiece. I did some googling and the only thing I could find was this guy in Laos that designed one on CAD and had it custom machined. Does anybody know of anyone making (or planning to make) an 8 string tune-o-matic? Has anyone ever had any parts custom machined?

    I don't think the low F# would be able to intonate on a tune-o-matic. The saddle wouldn't have enough travel. Should work on an 8 if it was tuned like a 7 with a high a or g though.

    negative,

    never seen one

    probably a good thing,
    iv heard about toms on lp's warping and cupping over time...
    and 8 would be a fair bit of floating metal between two posts....

    As I am the guy who was in Laos and I just found this thread via google I thought I reply.

    There is absolutely no problems with intonation.

    Obviously the important part is locating the bridge correctly ensuring that the scale is measured with the saddles at the front of the bridge. Well actually it probably more optimal to measure it with the saddle half way from the centre to the front.

    Here is my bridge fully intonated - note the saddle position for low F# (well F in this case) still has lots and lots of movement.

    You might notice I say 'was in Laos' as I am now in Singapore and as I am now in the developed world again I will be in the next few months discussing with a few companies about get these bridges in production. As the test version I got produced in Thailand came out pretty good - sure there is a few minor alterations needed but they are very minor and it plays and sound good.

    In terms of wear and tear - my intention like the test version is for them to be solid Stainless Steel (saddles included). They also have locking strews to stop movement of the bridges.

    When I get updates in terms of production I'll let people know - in the mean time any questions . . . let me know! :)

    Excellent news!!!
    I have been searching high and low for 8 string TOMs.
    I had considered custom machining, but that would be a pricey route I was not willing to go down at the time.

    To Mr Sje (or anyone who many know), what scale neck and gauge of strings are you using on that guitar?
    I notice the your F# and B (or I suppose F and C in your case) strings are intonated very close to the front of the bridge. In all other situations, the opposite is true.
    I am just curious as to why this is.
    Also, it is difficult to see in this picture, but has the bridge been routed such that it is at a small angle in respect to the finger board?

    Thanks for taking the time to search this out, join our little forum and reply to our concerns. You are a credit to the music community.

    sje that's really cool, hope you get the bridge into production :yesway:

    You should take more photos of that 8 string and post a thread in the Extended Range section, as I'm sure lots of people here would love to see more of your guitar.

    Hi,
    Well the reason is pretty simple - I angled the bridge as you would normally on a 6 string version and as I mentioned above I positioned the bridge at the scale length based on the saddle at the front of the bridge.

    Really it didn't need this amount of compensation since the bridge itself is actually wider than at 6 string so has more intonation adjustment. On that note the bridge has been designed completely from the ground up - it isn't just a copy of a 6 string with 2 more strings.

    The scale length on that guitar is 30.5" - this was used to allow the use of lighter low 7 & 8 string since when I designed the guitar my intention was to make one with as narrow a neck as possible. The Nut width is 50mm and the string spacing on the bridge is 70mm. The low 8 string is .068 and the other strings are a .054 set (if I recall rightly).

    Sabaidee koi bor yuu lao diao nee, koi yuu don muang Singapore . ..

    unfortunately due to this my guitar building is on hold since there is nowhere I can have a work shop here. So I am turning my attention to the parts mainly the bridges and pickups. Obviously I won't be making wooden bobbins like I made in that 8 string anymore.

    Were you building in Vientiane? What are you doing in Singapore and are you planning on going back?

    Hi there,
    Yes I was building in Vientiane. I am in Singapore for work so won't be back in Vientiane very often. :(

    But we'll see . .. ;)

    Thanks for chiming in sje. Imagine my surprise when I saw that you joined the forum just to respond to my post. Anyway please keep us up to date on the status of your bridge if you offer it for sale.

    Was just wondering about how I would go about finding an 8 string tune-o-matic. I would really like to see one like the tonepros made and have it recessed. this made my day really! keep us updated!

    Things are a bit slow at the mo. still getting the rest of my life sorted since the move - so things are on the back plate at the mo. Although I am gaining via my every day work better contacts in the manufacturing side in China so all being well I'll be able use them once I get to the point of a sample build.

    On the side of recessing - the actual bottom of my design is flat - so if the guitar is designed and built correctly then it's flush to the body anyway, without the need to recess.

    Anyway as when things progress I'll keep you informed.

    :)

    Well, sje's website has been down for several months so his 8 string TOM is on hiatus at the very least. Would a fixed bridge like the ones made by Hipshot work on a carved top LP style guitar?

    As long as the place in which the bridge is going to be mounted is flattened out, or the luthier you're going with makes a custom carved adapter plate of sorts.

    I have the capability to produce 8-string TOM bridges. If I could obtain the specfic technical information regarding the design and features it must have, then I will consider producing these bridges and getting it to market quickly and with high quality. I am happy to hear all your suggestions and advice regarding the 8-string TOM bridge.

    *** I am going to post this in the Dealer section now because of my relationship to Halo Guitars
