Ed, after a lot of research, I haven't been able to find identical or near identical pots for the Beta. To explain, basically a couple thing that's makes these pots unique is that they mount to the PCB board and also, they use half shafts, which are pretty much impossible to find except on older equipment. Most pots I have found are either the knurled type or the whole shafts. You could use the original knobs if you were to get a whole shaft type and trim it somehow. I'm going to be replacing my pots here pretty soon on my Beta Bass. So I will let you know what I am going to end up using as far as pot choice goes soon when I finally decide how much work I actually want to do on this thing.
