I was using CAPS AmpVTS and notice that some tone
knobs didn't work well.
end up trying tonestack plugin itself and it seems
that the problem (is
this a bug or its the way it really works?) is there, the Bass filter
apparently stops working about 0.5 to 1.0 , the Mid filter, on the other
way, apparently starts working in this zone, Treble seems to work
fine. Has anyone noticed something like that or even corrected this
It could be a bug, but it is not unlikely that the weird behaviour you
experience is due to the way the controls are intertwined -- the
original Fender tonestack (and its copies, like Marshall's) is not a
common 3-way equaliser design with independent filters.
If you haven't done so already, you can read about it here:
and if that does not
provide a satisfactory answer you're probably best off directing your
queries at David Yeh himself.
(It is possible I messed up David's code while refactoring, but if I
remember clearly I tested my changes for before-after equivalence of
