Stupid Me!!!

Discussion in 'Pickups & Electronics [BG]' started by bassguitar, Jan 5, 2006.

  1. I got some DiMarzio custom tapers for my Fender P yesterday. I put them in with a new cap, and output jack. First mod of this type for me, so of course I screwed up. Well sort of. :eek:

    Everything went in fine, and works great. :bassist: However the original chrome knobs don't fit on the DiMarzio split shaft pots, and I broke one of the shafts in the process of trying to squeeze it together a bit in efforts to make the knobs fit. D'oh! At least I didn't cut the new strings yet!

    So now I've got to get another pot, and two chrome DiMarzio knobs and take it all apart again tonight. Hopefully the store I got the pots at have DiMarzio knobs as well!

    The good thing though, is I can totally feel and hear a difference between the new pots and the old ones.

    Live and learn I suppose.

    well...I don't know how handy you are but,
    the pot should be a CTS pot..and you can open the can by bending the tabs, and carefully pulling the pot apart. The shaft is replaceable..and you can use one from a beat CTS pot with the same length shaft (if you happen to have one around). I like the brass shafts a bit better then the aluminum ones...they seem to hold up better.

    good luck!
  3. Thanks.

    I thought about that, but the only spares I have are the ones I replaced. The have aluminum shafts, and are shorter than the DiMarzio (brass) ones I replaced them with. The shafts on the new pots are also wider and longer so that's why they won't work with the original knobs. No big deal I guess, I'll get another one on the way home from work. 6.95 it was I think. The knobs will surely be more though.

    Turns out I was able to break the "stronger" brass ones!

    Have practice on Friday though, so I need to get her up and running right quick!

    Places like Guitarpartsresource sell sleeves that let you put solid-shaft knobs onto split-shaft pots. They provide just enough structure to keep from causing a problem like you had.

    Don't feel so bad. I had a friend bring over a Fender reverb tank for me to work on and he had ripped the shaft OUT of the pot because he didn't know there was a set-screw on the knob. That is much harder to repair because the pots are a lot harder to find.

    Worse comes to worse just play it with the bad shaft.

    I remember an repair article from bass player a while back where a guy's bass had split shafts and knobs that were for solid shafts. The knobs had broken half of one of the splits off, so the luthier cut part of a wooden dowel rod off and glued it in there to give the knob some thing to bite on. Then he sliced up a guitar pick to fit in the other split shaft to keep it from happening there.
  6. Funny, that's exactly what I did. The only knobs I could find at the closest store to me were for solid shafts. So I cut a little piece of metal as a spacer and glued it in between the unbroken and broken side. Not bad, though the knob isn't on exactly straight so it's a tiny bit wobbly. I'll replace the pot again eventually.
