How to fix a bent pot shaft?

[Bassamatic]

Gluing a new shaft on is a very good idea, but not super glue- the surfaces will not be smooth enough. Use some epoxy and be careful it does not glue the shaft to the pot, and then be VERY careful with it from now on.

Bring it to Rogue Music on 30th Street. Nice guys, reasonable prices, reasonably good repair work. If they can't take the repair in, I'm sure they can direct you to someone who can.
Talk to Clay or Ian if possible... very easy-going guys.

Good luck!

FYI - PCB mounted pots are much more reliable and much less labor than hard wired pots - that is why they are used.

They are, in fact, much less laborious to install, which means lower production costs and, hopefully, a lower price point for the consumer. I can think of no reason whatsoever why a board-mounted pot would be more reliable.

You could try to straighten it by gently bending it back to original alignment with pliers. (of course remove the knob first). This could restore it. It also could damage the internal wiper to resistor band contact rendering the pot useless. As others have said order an equivalent pot off ebay, and solder it in place. No big deal...

Your mis-adventures have been forseen as the scripture reads:

"If it's stuck, force it. If it breaks, that's okay...it needed to be repaired anyway."

Thanks Zooberwerx, I now have a new sig.

Exactly! The only advantage is making assembly at the factory more efficient. If the PCB mounted pots also use mounting nuts, then a PCB with multiple pots can place stress upon the PCB solder joints if the mounting face of the pots are not perfectly aligned when soldered to the PCB. If the PCB mounted pots do not use a mounting nut for fastening to the panel/enclosure... then every time an adjustment is made, those mechanical forces are transferred directly to the PCB traces and solder joints.

Would it be possible to drill a hole in the center of the shaft deep enough that you could set a little headless machine screw in there, maybe held in with epoxy, then a sleeve around it to fit the original knob? That way you wouldn't have to mess with the electronics, and seems like it would be a lot stronger than something just glued to a semi-flat surface.

So I called MXR and explained the situation. They're sending me a brand new pot, free of charge even though I'm not the original owner.

While I'm still surprised at how easily it was damaged, at least we can all give three cheers for their customer service.
