Help me find this part, pcb mount potentiometer

[Dotina]

The expression pedal of my Zoom G3X is acting funny. I am pretty sure the potentiometer needs to be replaced. All I can tell is that this is some alps pcb-mount potentiometer, very similar to this one

Any idea of what the total resistance, taper, etc should be for my Zoom pedal? Thank you.

Alps are good pots. If yours is indeed an Alp (how did you confirm that ?), the RK11 series is readily available from major suppliers, eg ..

If you can't trace it exactly, and the pot has not stopped working completely, you might have to measure it with a multimeter (out of circuit) to get its specs. That would also tell you if the pot is actually bad or not.

Based on the 103B marking I would guess it’s a 10K linear pot (103 designating 10K, the B designating linear taper).

How do the solder joints on the other side of the PCB look? Pot could be fine...

That 103 does mean 10 kOhm. The 'B' may be log taper... for some reason it looks like that parameter is used different on their 11mm series and 12mm series. You'd probably have to get that geared bushing off to see what's underneath, taking careful measurements of the shaft. They have a few models that look the same, and I didn't see anything that made sense of "445C".

If you could find someone at Zoom who could tell you what it is, they may just send you one. And it may be possible that it's a custom run with a shaft made for that gear.
