Title: Tone Control/Stack Articles?
Post by: aziltz on March 20, 2009, 11:52:06 PM
Are there any noteworthy articles on Tone Control and Tone Stacks?  I've read Jack Orman's stuff over at AMZ, but I'm looking for some new reading.

I was toying around with the clipping section of a TS-Type Pedal, and I wanted to try different tone networks/controls/stacks after it.

Any book on analog filter design will get you a good basis.  If you want something a little more hands on, Duncan's tone stack calculator helps you see what different component values translate into in terms of frequency response.

I have Duncan's Calculator as well.  I think I was hoping to find some information on signal drop through tone stacks and the amount of clean gain you would need before it to drive it.

Hi, Two places that I use is http://amps.zugster.net/articles/tone-stacks (http://amps.zugster.net/articles/tone-stacks) the rest of the site is also very interesting. here you got lots of examples.

To calculate I use http://www.muzique.com/schem/filter.htm (http://www.muzique.com/schem/filter.htm) simpel but good. but this is prob. old news for you.

The calculator tells you that!

i dont quite understand the basics yet.

The plot on the right shows you the output level vs frequency. At the top is 0dB, ie the same level out. Then it shows you how much signal is lost at each frequency. Hit the sweep button to see the range, then you can spot the maximum and average levels and work out the makeup gain needed from that.

Sorry I was unclear.  I understand what the Calculator is doing.  I haven't yet taken the time to discover and investigate what kind of gain stage is well suited to driving a tone stack vs a simple tone roll off.
