    Title says it all. But I need to know if anyone has done so how they went about it, or if you know anyone who has (and what they did) I'm definitely taking it to a luthier for the drilling part, but as for the set up, I'm doing that myself. So what works best for this?

    Success? Horror Stories? Or just plain random stories?

    I also plan on defretting it eventually (probably first, but there's MUCH more advise on that, then converting to an 8-string)

    Here's the real kicker... This is my only bass :D

    If the nut is less than 1.75" wide, I wouldn't do it. If the back of the headstock where it joins the neck is thin, with no volute, I wouldn't do it. If the neck flexes easily (while wearing the bass, grab the upper horn with one hand and the headstock with the other, and flex) I wouldn't do it.

    If the nut is wide enough, the headstock joint is thick enough, and the neck is stiff enough, then hellz yeah go for it.

    Thanks man.

    +1.75 - Check (Barely)
    Volute - Check

    It's a pretty thin neck despite the volute. Including that its about .90"

    The neck is pretty resistant to flexing. I'm not positive of the neck wood, I've read its hard maple/rosewood (neck-thru)
  5. but don't remove the frets!!!

    yeah, do not remove the frets. I have a Marcus Miller 4 string with no frets. Its cool at first, but you will kick yourself. Believe me

    What's wrong with the fret removal?:confused:

    Most people on the defretting forum are elated with how their basses sound. And my playing is better suited for a fretless.

    I've already got the wood strips picked out that I'm going to be replacing the frets with. There's always sand paper, tape and a soldering iron lying around in a basement. All I need is the lacquer and fret removal tool (and time)

    Years later, after massive fret abuse... It's now a fretless.

    I didn't go the 8 string route, but with a whammy bar. And she's since regained status as no. 1.

    i believe they mean don't defret an 8-string, probably due to intonation issues.

    as for the 8-string conversion itself, i did this once with a fender-spec body. i used a warmoth 8-string conversion neck and a schaller roller 8-string bridge (separate saddles for each string to alleviate intonation issues). worked like a charm, and was also reversible.

    Just remember that the neck will have twice the tension on it, so assuming the neck is substantial enough, all the hardware should be double-checked for integrity and proper installation. I would recommend that one of the sets, possibly the octave set in order to assure the same sustain as the unison set, be strung through-body to keep excess shear tension off the bridge screws.
  11. Awesome looking bass! Nice seeing someone else with a fretless and a trem. Here's mine
