Lets say I have a full shred and think its too bright/has too much treble. If I just had a volume, and dropped it to 250K, would it make a big difference, or just a little difference?
I don't know exactly how much difference, in terms of what measurements can be taken, but it's enough of a difference to easily notice by ear. That said, having too much treble is easy to fix 99% of the time without changing any parts at all.
