3 Band Active tonestack

[POTL]

friends please share the good scheme 3 Band Active(with op amp) tonestack with frequency response calculator
In Google there are a lot of different schemes, but no descriptions of how to calculate frequency
Many passive tonstack also without annotation

[POTL]

for example, this scheme looks attractive and simple, but how to calculate frequency response?

Save yourself the pain and wads of paper working out all the calculations,,, just Download a circuit simulator,,, will put you way ahead much faster than pen and paper.

Hi
I only know a program that is mentioned in the book of Brian Vampler
But there is only passive circuit
If there are any programs that share please)

For a long time I just used a student version of Circuitmaker6 which is limited to 50 components but for simple pedal builders it covers a lot of ground and more than capable of simulating tone control circuits. That may not run on later versions of windows but ran like a dream up until win7.
I finally got hold of Cmaker2k but frankly I found version6 easier to use.

I can't find the original link but this link seems to be working; http://users.wfu.edu/bonin/Electronics_230/phy230.html
A good tutorial can be found here; http://www.zen22142.zen.co.uk/eda.htm
You may find several other sim brands on here also so take your pic? I Notice the author mentioned that Cmaker was the first sim he used
No doubt experts would likely see limitations with Cmaker6 but I'm not a teck jockey so this was all I needed. If you are new to sims then there is a learning curve involved but if you understand the basics of analog circuits it won't take too long to work out the tricks.

Always remember No matter how good your simulation says the design works you still need to build the prototype First BEFORE you commit to a build. If you don't then be prepared to waste a lot of time building landfill.

Same for most circuits on forums,, Yes it may work brilliantly on his rig but may sound like crud on your gear.
If you want a different *Passive* tone circuit you can always try my hiwatt inspired tone circuit,, just google Phabbtone. If it's not here on FSB it will be over at SSguitar forum.
Have fun,, Phil.

I usually just use spice

I agree : save yourself the pain.

Most softwares that I have tried are way overkill for what we typically need in stompbox design.

The software below is perfect for designing small circuits IMO. It has some limitations (among others depletion FET's are not available in the free version) but it's damn near perfect for evaluating circuit snippets.
Extremely newbee-friendly, extremely small program and it doesn't fuck with your windows registry
Give it a try.

I was puzzled and then the spices lol
Thanks Brian
