If there's no markings on it how do you tell that if it's a audio or linear pot??
Set it to half-way through the travel, then measure ohms from the ground side terminal to the wiper (middle) terminal. If the reading is, more or less, half of the pot's rated resistance, it's a linear.
If it's a lot less than half, it's audio.
Thank you I just tested two of them and one is linear one is reversed.
Yeah, I was going to add, if it's a lot more than half, measured to ground side, then it's a reverse audio taper. Which is not to be confused with an anti-log reverse rotation pot.
One more question, can you hear any sound difference between let's say a
1.012meg and a .867meg pot's in a amp?
As a volume/gain/level pot, probably not. In a tonestack, maybe.
I'm putting it in my Deluxe amp, it's the tone/power switch knob.
