Just finished the mods today with a chrome Dusenberg Les Trem II and upgraded controls. Volume is 1M audio taper and tone is 1M linear taper. Strange thing about the tone control is the tone only seems to change between 0 and 4. Above 4 is full treble. Any ideas what might cause that? Maybe it should be an audio taper pot?

Yeah, you have your pots the wrong way round.
You mean wired in reverse? The volume pot is fine. It's just the tone pot that's full treble between 4 and 10.

Right. Don't use linear, use audio. Also, don't use 1 Meg. 250K gives the best response to movement of the knob.
Edit 3/15/22: I don't think I'd hear the difference, but to avoid any signal loss through the 250k pot, use a no-load pot (or make one from a standard pot).

Sounds good. Thank you.
