Simmed a LPB like circuit with a 100K and 500k output volume control
Think about the added output series resistance when the volume control is not at max
left side is a simple guitar sim and cable
LPB like circuit
.1uf output cap, changing this will change the low end
output of wiper to 390pf, 10 feet of 39pf a foot cable and I picked a 470K as the simple input resistance of the next stage you can change this to 1 meg etc.
Also the high pass will change with different C1 values
Now sim a FF like circuit and try different output control values, coupling cap values, cable length, next stage input resistance loading...
