The last third of the 500kB gain pot in my Neutrino seems to not really have any effect on the sound. Is this normal?
I'll check mine when I get home from work. I built it and rocked it a few minutes, but that's about it.
Yeah, with a linear pot, the gain will come up pretty quickly. In that case, I wouldn't expect the last bit of travel to give you much more. A log/audio pot will spread the control effect over a broader range of rotation.
