Tone frequency plots for passive bass ?

Hi All,
I know there is a great tool for finding the knee on amp/pedal tone circuits - but can't find anything or even a plot for the passive one in a bass. I am interested in seeing the cutoff freqs of various caps in a bass. Since the coil is an inductor, I don't see you can use the dc resistance as that would vary with freq. Even ballparks are something I can't seem to find. Example in a P bass with a .022, .047 and a .1 - how do you determine the cutoff freq? Anyone else ever look into this?
Thanks, David

Bump for a panel stumper or a mental case who thinks too much about insignificant bytes.

Maybe check out this thread...

Capacitors in relation to a varitone type application

Towards the end there are a few links that might be what you are looking for?

Aloha Friday,
Thanks - Looks like your first quesiont is what I am looking for too. Don't ever find the answer to the frequency question, but close enough to get what we need to do I guess. I'd seen the tone switch by Darkhorse thread in the past, did you ever put one together? How did you like it? PSPICE page is good, hadn't seen that one before. Have read some of Helmuth as well. Nice double p btw!
