It looks like a 16mm Alpha vertical PC mount pot.

Check here or here. Its value is 500k, audio (log) taper.

 

It's a custom pot, needs to be ordered through a Fender service center.

Since that's a double sided PCB with plated through holes, you need to be very careful not to damage the plating.

 

This is a very good place to buy Fender parts. They are a Fennder service center and parts distributor. Send them an email with all the details. They should be able to help you.

Fender amp potentiometers

 

With that back lug, I kind of figured that. Probably custom length on all the legs, too.

 

I don't know, but Fender buys pots by the millions so they can get whatever they want/need.

 

It’s a style that Fender uses. It adds stability that helps prevent broken solder joints.





Although these type of frames do a better job but require enough space to mount.

 

2 different orientations

 

True. I've seen both orientations available. With all the metal, people find the bottom one difficult to unsolder. I snip the metal frame, then unsolder the snapin pins.

I use a lot of these Alpha pots, with a properly nut in place on a firm plate, it's hard to imagine how a top mounted pot could break like in the image from the OP. Folks always seem to find a way.

 

I see a fair number of PCBs ruined by folks (including some techs) who have no idea how to properly remove parts without damaging the PCB. A simple repair can easily turn into an expensive re-work or sometimes beyond economical or reliable repair.

Yes, always cut the part out and remove (GENTLY) the pins one by one. Suction is usually much gentler on the pcb than wick, but either can become disastrous with "ham fists".

 

It's a spider style pot, I found several audio taper ones but finding an audio taper 500k eluded my 5min search.

 

Note that there are different terminal heights, bushing heights, shaft lengths and styles within this series. All of these need to match, which is why I suggested contacting an authorized Fender service/parts center.

 

I'm not actually disagreeing with any of that, just stating that you can find them outside of a service center with the correct physical specs.

It's not like we're talking about finding esoteric milspec parts that aren't in production anymore.

 

Not necessarily, they are build to order parts generally and not available or shocked off the shelf. I use some of these types of parts which are only available in OEM quantities as built to order parts.
