Title: "better TMB Tone Stack" post elsewhere
Post by: PRR on September 02, 2020, 10:00:03 pm: A Better TMB Tone Stack (https://www.diyaudio.com/forums/instruments-and-amps/359601-tmb-tone-stack.html) at DIY Audio forum.

At a glance: the plan looks rational. I don't know how it works on the musical ear. But it is about a dollar's worth of parts over what Leo used so it is a cheap and reversible experiment.

With respect, Tubenit

Oooops! I knew the *section* was Public but did not realize the *Attaches* were limited (of course they are).

Tubeswell got the schematic. There are six plots showing the wide variety of possible curves. The extremes are often too brutal to use, but gentle use of a sharp knife may be useful. On the plots, the dotty lines are Phase; we do NOT care here, but the plotter option to not plot phase is well hidden in that software.
