What a bizarre coincidence! I was just contemplating the ToneStyler when I checked in with this thread...

I noticed at the Stellartone website that they're claiming to reduce "pickup loading" via the use of small capacitors. I really don't remember RC circuit behaviors from school at all, but I know that Bill's pickups are designed to see "normal" loads from the pots. I wonder if the ToneStyler is really that compatible?

PeteMK1 and I had some discussion awhile back about DIY replacements for the standard tone control along similar lines to the ToneStyler. You'd simply use a 6-way rotary switch and put in your own R's and C's. I feel like 14 combinations is too many to make sense of, but six should be about right. Nevertheless, I am lazy and dont' care to figure out my own R and C values through experimentation.

Pete pointed out in the other post that Helmuth Lemme has produced a relatively economical device, called the C-switch,
that is already wired up and cased in durable epoxy. I haven't contacted Mr. Lemme yet about a possible international transaction, so I was hoping to get by with a minimally improved tone pot for the time being...
