    I am wanting to either convert or build an 8-string octave bass. I am trying to keep the price as low as possible, and I am not as concerned about looks as much as functionality.

    Does anyone have any suggestions of where to find pre-made necks other than Warmouth?

    Does anyone here have experience converting a 4-string to and 8-string octave bass?

    Thank you for any input or suggestions.

  4. Ideally, you want to find a bass with a good headstock layout ( lots of space for 4 more tuners and good angles for the string paths leaving the nut) and you also want to find a bass with a fairly wide nut that will allow 8 strings. I would suggest perhaps a p-bass with the 1 5/8" spaced nut or even the 1 3/4" nut. The headstock would give plenty of room for 4 guitar tuners, but they would have to be in-line... Maybe a 2+2 neck would be better?

    I'm highly opinionated and extremely self-assured
  6. Carvin will be glad to see you a neck with a blank paddle head that you can cut to whatever you want.
    I think maybe a 5 string blank neck would give you the extra width you need.
