    if i get a neck that is made for it. and that it fits in the neck pocket is it possible? and can i do this so that when i wanted to i could change it back to a four string with out any damage?
    where can i get a 8 string bridge? i can drill it to fit the existing holes on my fender.
    and it would be nice if i could get a fender shaped head stock also.
    do i use guitar tuners for the octave strings?
    if so then i have all of the turners.
    and i have experince in building basses and guitars. i just need to know where i can get the parts and if you have seen this before?

    i can even make my own bridge if i had to.
    how exactly does a 8 string bridge have to be?
    string spacing?

  3. just add :

    - some holes to the bridge
    - some grooves (sp?) to the nut and sadles
    - guitar-tuners on the headstock
    - some strings

    and you're done :)

    really? it is that easy?
    what side do the octave strings go on?
    does it matter?
    i was going to make a bridge with extra saddles so i can intonate the ocatve strings. do i actually have to do this?
    and would a warmoth 8 string neck be worth while or should i get a wd replacement neck and put 4 more holes for the turners?
    it will be a whole lot cheaper that way.

    Trade it in for a used Dean Rhapsody 8-string.

    Getting the strings properly aligned over a pickup made for 8 strings would be a headache, (for me, anyway).

    Our 8-string is also built extra-strong to take the extra string tension, and has room on the headstock to mount all those tuners.

    The Schaller 8-string bridge has adjustable intonation for all 8-strings and bolts on from the top with no string-through drilling or ferrule mounting necessary. Schaller has discontinued this model, but we have placed an order for an exclusive run of the bridges for Warmoth.

    We love 8-strings!

  9. Definitely Warmoth, man. Definitely.

    BWB, how does the Warmoth 8-string neck play? I like 'em thick (my FBB 5-string is 0.90" or maybe even 0.95" thick and asymmetric), so the Fatback profile looks pretty tasty.
  10. Well, excuse this old fogey for doubting, but, how in the world does one play 8 strings on a neck the width of a 4- string bass? You must have really thin fingers.

    like a 12 string guitar!

    Well, X, that makes two of we "old doubting fogeys." At one time in the same band, one of our lead guitarist's guitars was Rick 12-string convertible and the rhythm player had a Hagstrom 12-string. These were completely different animals as opposed to a bass with sympathetic strings.

    The incredible stress such a bass puts on the bridge, neck, and headstock, without attention given to increasing the neck wood-mass and/or wood stiffness factors is just nutz! More importantly, mopar, - I just think you desperately need to appreciate the importance of the pickup factor. mopar - you would have a single pole piece trying to pickup TWO vibrating strings. The neck, headstock, and bridge are virtually meaningless if you don't have pickups that "track" the movements of the strings.

    But, Xavier G, let mopar find out the hard way. He'll either turn our heads around (I truly hope mopar has a good result or he'll, (more likely), throw money down the sewer.

    In all sincerity, I hope just a simple hardware change works for him. I admire those who test the supposed limits.

    But Xavier is a true pro who has seen `em come and go like I have. I have ultimate respect for the X-man.

    In short, I bet dollars to donuts a simple hardware change. (i.e. nut/bridge/headstock) is doomed to failure unless you like sounding like microwaved doggie doo-doo.

    Aha, but Jazz pickups have two polepieces per string, and normally the single strings are between, rather than right over them. With the 8-string conversion parts, the strings pass more or less right over the polepieces on standard Jazz pickups.

    By the way, these necks are built like a tank - 1" thick all the way up, 5-piece backs with bubinga stringers. I ran the specs on this neck through my neck stiffness calculations, and the 8-stringer with rosewood board should be at least 85% stiffer than one of our maple/maple Jazz necks with steel reinforcements. Pau Ferro and Ebony-board necks would be even stiffer - certainly enough to handle the extra tension.

    I'd consider another bass. Maybe a Hamer or something else. Sounds like a lot of work and not being a luthier won't help

    My Hagstrom 8 actually has a thinner neck and same nut width as my MIA Jazz. My only complaint there is that there isn't much taper on the Hagstrom neck. It's about the same width all the way down. But it plays great! I don't always have you use a pick, and I'd say I have fairly large fingers (damn arthritis at age 19!).
    I know the Deans and Hamers are coming with larger necks, and they are more comfortable to play with all those strings, but this Hagstrom is Fast!
    My opinion on the original topic is the same as Rob's there. I'd try to pickup a used Hamer or Dean. You may be able to find one for the same price range that you're looking at for a new neck, nut, bridge, etc.
  16. Yeah, Jimi Hendrix went shopping for a 12 string (guitar) one day and ended up with one of those :) (he was a bit stoned and failed to notice the 4 missing strings). For a while, he had 2 bassists in his band, and he didn't even know he was one of them!

    I'm just skeptical, but that's not to say mopar's project won't work for him. It wouldn't work for me.

    Good luck, mopar! Let us know what you decide, and how it turns out if you decide to do this.
