Differences in A500K & B500K Pots:

[Inspector #20]

I used some Alpha pots to make a temporary harness.

IIRC, the A500K is Audio Taper and the B500K is Linear Taper???



Audio is even/gradual roll off and Linear is sudden drop, or?????

Not really. Linear is actually the even rolloff, meaning a more or less 1:1 relationship between knob movement and taper:

But that's not how our ears work, so we perceive it to sound like if falls off a cliff. Audio taper pots were designed to compensate for our natural deficiency.

Perfect Explanation!!!!

I use audio for volume and linear for tone. But I ran across this on another forum.

in theory audio taper is what you want for volume contols, but what i have found is that if you use a cranked up tube amp linear pots can work better. i use a humbucker loaded guitar straight into a deluxe reverb and turn it up to 6. at that point the amp is cooking really nicely giving me a sweet overdriven tone. in order to clean it up i roll back the volume control. using a linear taper pot i have much more control over the clean to dirty ratio of the tone. with an audio taper it goes from dirty to cleanish very quickly making it hard to dial in shades of dirt.

if dont use an amp cranked up to get your tone then this isnt a consideration but i wanted to clarify why i said "i used to prefer audio but ive been happier with linear recently
