push pull pot

Post by billstets » Thu Apr 05, 2012 12:14 pm

I'm currently running my JTM45 as what I believe to be bass spec, no cap on the volume pot. I was thinking it might be cool to put a cap on a push\pull volume pot, so that I can have lead sepc if I pull it out. Does anyone know of a pot that might work for this application?

hey thanks a lot. Do you know if the Marshall type knobs will fit on that shaft?

The push pull knob shaft appears to be the same diameter (1/4") as say the Alpha pots. It will require enlarging a new knob slightly with a drill bit (not powered but by hand). I found it easiest to start the enlarging process with a 15/64" bit and then finish with 1/4". Take a look at the link below for more information. Maybe your old knob is already sized and then in this case it should just slip right on. Scott
