How to implement Baxandall tone stack

[teemuk]

IMHO the James is for tracks which are already mixed and balanced and tone-shaped, but need mild general tweaking (either way) for the listener's room and taste. Playback Systems. It's not as useful for music Creation.

IMHO, it controls bass and treble without the stupid interaction of the generic "FMV" stack and does its job very well. The signal doesn't care whether its comes from a pickup of a musical instrument or from a prerecorded media.

If you feel like you're lacking the non-linearity created by the traditional mid-range notch you can always introduce it externally and this is exactly what several amplifiers using generic James/Baxandall stack do.

Yes it has been used in electric guitar amps, but not much, and perhaps mainly because it was SO common in Hi-Fi.

Actually you can find that type of tone control from several hundreds of guitar and bass guitar amps, including Orange, Sunn, Gibson, Ampeg, Tech 21, Polytone, Gallien&Krueger, Acoustic Control, Pearce ...to name just few from top of the head. Even the highly revered Fender Blonde Twin amp has one. The "Big Muff" tone stack is actually a patented design for a HiFi amp that's who knows how old and what about all kinds of gain stage or phase splitter circuits and - in fact - pretty much ALL generic amp circuits; most of them are commonly used in this so-called "HiFi" too so it's a kind of weak argument.
