Is there a better calculator around for tone controls which allows any combination of R&C to be used? I don't wish to use a circuit simulation program..
I have the offending Fender Deluxe on my and will eventually figure a decent mod so it sounds better - I hope - and as a result of applied science rather than applied BS.

Hi Patrick,
why not measure the values of the aged components of the tonestack and
"clone it"?
The older good Fender pots usually don't change R values much.
I plotted the response carefully though.
second - the big variable in "Sound" is the speaker. It changes more
than a little bit. Especially with the DRRI.
Well yes, but Its worth a shot to re-engineer the tone controls.
I have heard fabulous music from modern speakers, even though they have a bad reputation with many musos who I sometimes think have irrational fondness to items from the "good old days". Not all their opinions are wrong though, and this time the amp owner was dead right about what he hears. OK, let me try something rather than blindly copying, and if the guy is happy, then mission accomplished and I am the wiser for it.
AFAIK the TSC is the only readily available software. And it only does
the tonestack. It does not cover the "bright switch" - or cap, nor the
cap across the isolation resistor of the reverb and so on...
Yes, seems like TSC is all there is, and was made up by a Mr Woodgate who seems non-contactable. I may be FORCED to learn how to simulate with R&C and a decent simulation program that accurately predicts response of any R&C network one is likely to compose.
Ampeg have a Baxandal type of tone control, no cheapy silly "stacks".
I'll have another look at Ampeg circuits. ,have

Hi Patrick,
don't laugh - I deleted some lines about those old ampegs and the
Baxandall... Did I really delete them? =
the components I'd consider to measure and clone ain't the pots, but the
caps, the slope resistor and the cathode caps (them throughout the whole
amp). It's the whole system - not just the tone stack. Differnces might
be subtle. You are dealing with - humans - worse: artisans
For me the speakers themselves don't need to be "old". IMHO the
particular OEM-Emi in the DRRI is simply a piece of ****. It does not do
any justice to the capabiliies of the amp.
New speakers ain't generally bad. You've got a hunch of choices
nowadays. IMHO there are some Speakers to consider with a DR:
EMI RedFang,
Celestion Alnico Blue,
Jensen Electric Lightning,
the WGS Blackhawk,
Celestion G12-65;
EV-12L
et al
It's simply a matter of taste.... Myself, still opinionated, that
"better" is not always necessarily "BETTER"..... But I hav e to confess:
I'm a convinced player of an old 5E3 Deluxe Repro with an 12" Alnico
Blue RI - far away from technically perfect, but a real fun machine ;-)
