Marshall Tone Stack Q

[lowell]

If you turn the MID pot UP to 10 are you moving the cap on the wiper up towards the BASS pot or down towards ground?

[Albert Kreuzer]

Towards the bass pot.

Thanks AK.

If I can ask....So what happens exactly?
The Mid is 25k and the Bass is 1M. What takes place as the Mid pot turns to 10?
Thank You
I am assuming a Marshall Tone stack is like the plexi below......

The TC caps and resistors provide a dip at a certain mid frequency; those 10K or 25K in series with the capacitor which goes to ground, dampen that dip, so "you have more mids", in fact they get less attenuated.
Google TSC , Duncan Tone Stack calculator, which will let you play with components values and draw the response curve. Very useful.
See by yourself what the mid pot does.

I am an idiot for not downloading that long ago. That is an amazing experience. Almost like the first time I had.......Well, lets just say that is an awesome tool. Thank You for the response and the nudge to acquire the Duncan TSC.
Thanks
