Well this is just an idea I've been toying around with, but I hope to start working on it once summer rolls around the corner and I'm finished with school. I am in no shape or form a builder of any sort, but I love modding basses, and I think this would be a pretty cool (and difficult!) mod to do. The basic idea is to take a cheapo fretless jazz, either a squier VM or an SX, load it up with some nice pickups and hardware, and modify the headstock to hold 8 tuning pegs to make it an 8 string, double octave coursed bass. I'll put much more detail into all the exact specs later, but the first thing that I want TB's input on is if this is even possible. My idea was to fill up all the original holes, and then drill 8 new ones (4 big, 4 small). To make room for that I figured it would be 6(3 big, 3 small) tuners on the side that the holes originally were one and 2 tuners(1 big, 1 small) on the other side. Is there enough space on a Jazz headstock to accommodate that? if not, I'm perfectly fine with ordering an 8 string neck from Warmoth and putting it on an SX or Squier body. In fact, that might be an even better option since I could get a nice ebony fingerboard, but my plan was to keep it as "original jazz" as possible, and that included the jazz bass headstock. So, any ideas or suggestions? I appreciate it, Thanks!
