Still looking and need a Push / Pull Potentiometer that controls the Vibrato - Tremelo on this amp....Kustom 50-2
The shaft has been broken on my amp....
Is there any other amplifiers that has this control on them?
Thanks for your help...

No other Kustom amp uses a 500k pot like this with a push pull switch on its rear.

Antique electronics supply has part number r-vs-500ka pot with the needed switch on its back, but you will need to hard wire this switch into the board since it's not a circuit board Mount style .

Also this comes with a long shaft that you will have to hacksaw back to the length you need.
If you use this when you cut it be double sure no metal filings get into the pot, so tape it off.

Antique Electronics has a Peavey 50K pot that has the push pull switch (part number R-VPV-50KL-SW) that mounts just like the Kustom pots do.

You would have to take the original 300K pot apart and fit the resistance wafer into the new pots casing, but it would get you a working replacement.

I did find the switch and the shaft would be long enough and would wire into the board but this is a " sweep " switch from left to right with the center being in the " off " position , correct??

If I read the schematic correctly, this is the speed control for the trem/vib circuit. Left (CCW) is slow and right (CW) is fast.

The pull switch selects between trem and vibrato.

Correct on the 500 k pot....
I have gotten on from eBay that has the same makeup as the old pot EXCEPT it's a 1.5 k so I'll remove the shaft and fit it into my old one...
I'd like to add a picture here If I could
Thanks
