The bandwidth pot for the slap chop (systech harmonic energizer) is listed at 5KB (linear). In my recently finished build (photos when I get some fancy knobs in), the interesting part of this pot is around 80 - 90% clockwise. Would a 5KC (reverse logarithmic) give me a greater range of sweet-spot-ness?
Yes, a reverse log will spread out the range at the CW end of the pot.
