I swapped pots in my Dearmond M75, the volume pot had a dea spot and I thought this would be a good reason to swap pots and caps.<br /> <br /> I ended up using Alpha 500K pots, Audio Taper for Volume ad Linear for Tone.<br /> <br /> I decoupled the volume circuit, added a treble bleed mod with .001uF Orange Drops and 150K-ohm 1/4-watt resistors, and the tone circuits got Orange Drop 022uF caps.<br /> <br /> The strange thing is, now when I roll down the tone circuits, they only seem to work with about the last 1/4 throw.<br /> <br /> I made sure the Volumes used the "A" pots and the tones used the "B" pots.<br /> <br /> Any ideas?

That is what lefties experience when manufacturers use their regular righty pots and wire them lefty. Iâm referring to audio taper tone pots. <br /> <br /> I always use audio taper pots for volume and tone.

Thanks Leftee, I might just put the original tone pots back and just swap the caps.
