My knob's fallen off...

    Yes, the one on my Geddy Lee has come off. It's the smaller one, that controls the tone. I put the bass into my gig back, took it out later on, and the knob had fallen off. I have no idea how. I also have no idea how to put it back on. The peg that the plastic knob goes onto is completely smooth, and thought they worked by being grooved, to grip the plastic top. I can click the knob back on, but it just spins freely. The actual metal rod bit still controls the tone, so I'm just at a loss as to how the damn thing gets back on.

  3. :D Hahaha.. good one..

    Check the knob. On its side there is probably a set screw. Slotted head or allen-head. Align the knob where you want it on the shaft, and tighten it up a BIT.. Don't strip it by overtightening, ok? Then you'd be buying a new knob...

  4. Or if it's not that way, glue it.
  5. It's either a set-screw or press fit (ribs or grooves on pot shaft and inside the knob)..

    If, by some weird chance that it's not, don't use GLUE. Perhaps wrap the tonepot shaft with a layer (or more) of scotch tape, until the knob will stay put when you press-fit it on.

    Unchain I've seen footage.

    See if the split shaft got squished together. If so, shove a screwdriver in there and pull it apart.

    I found a little space for an allen key, so once I find one that fits I'll get it on. Thanks for the help, I have no idea why it came loose, though.
