Quick question Fender TS

Well they know how to keep their craft secrets and takes with in graves.

Dear friend, there are no secrets. Only secret is human ignorance.
No one was born learned. Only depends from individual whether wants to learn something doesn't know, or only to copy/paste else's experience.
Anyone who doesn't know, ignorance conceals with word it is secret.

Well they know how to keep their craft secrets and takes with in graves. Reinvented the wheel is not quite simple task. The analogic circuits are history in our universities.

Yep. We are the LAST generation to enjoy and appreciate analog technology. And we will be the only ones to recognize what is lost (for the most part, there's always some residual crankiness ) Enjoy it while it lasts. What else can I say,.. Except that what's following isn't all that bad. Different from what "we" know, but not necessarily bad. (Okay... I think it's bad, but I try to keep an open mind on these matters. Especially since there's not much I can do about it!)

I'm not sure if we ever can get totally rid of analog technology. Amps are one example: we can transform a lot of signal processing from analog domain to digital but we STILL need analog input and output filters, converter stages, power amps (even if class-D), power supplies, and so on. Even underlying principles of integrated digital chips are analog.

Well sure. Okay. True. But I'm not so much talking about the creation of watts as the pleasant "consequences" of using analog tech for small signal amplification and signal processing. This is something that is now being "simulated". But some day, when the last of the old guard kicks, there will be no one who has ears trained to accept these tonal anomalies and they won't even be simulated digitally anymore. I don't doubt that there will still be electric guitars in a hundred years. But I wonder what they'll sound like.?.

Despite any opinions to the contrary, I would be perfectly happy to recommend the 100K log pot for bass control. In the Fender tone stack it's ordinarily used as a rheostat = variable resistor, iow only 2 terminals. The amount of bass proportional to the resistance selected, simple enough. True most folks - with any sense - don't spin the bass knob up very far. Excess bass eats up power, it's unnecessary, and makes tone flubby & woofy. Old sound engineer advice: the wider you open the window (bandwidth) the more crap flies in. IOW there's no need for excess bass. If your 100K bass control makes you happy, so be it. Keep that bass trim & tight. Also it has the advantage of spreading the useful control area over a wider turn of the potentiometer/rheostat. Gets my vote!

FWIW I've used 50K bass pots at times. Never a complaint. Plenty of oomph when turned way up, and tone doesn't sound thin & nasty at all. Well, unless the treble's cranked up and bright switch on. Maybe if you're using metal cone speakers especially 10's as well. IMHO bass guitar needs 15's, even 18's if you can deal with them.

Thanks Leo. At first glance the "problem" with this circuit is its implementation in my opinion. It should have a high pass filter at its input with a pole around...say 70-80 cps. A 22 nF cap between plate and tone stack will improve things a lot I think. Otherwise it is very difficult to deal with lower frequencies which pass in block once you open the bass pot a bit...Saw later versions instaled a high pass cap between tone stack and volume pot- which make the tone thin rather to solve the problem in bass.

Nothing wrong with that idea, 22nF between plate and tone stack. Easy, cheap experiment. You could try different values if you find it works "in principle" but needs some tweaking. FWIW I've run across some amps that employ a cap in that way, then they use cheap "chiclet" low voltage caps for the tone stack. (Chiclet = square little chewing gum candy in USA, the caps resemble those.) I thought manufacturer of those amps did it to save money. But it's not a bad idea to limit low frequency response to some extent.

Let us know how it works for you.
