Need help for increasing treble tone of Angry charlie v3 clone

[ali1111]

Hi friends
I've  made a clone of Angry charlie V3, its sounds amazing and have a nice and warm  distortion but i think it has less treble, what is your recommendations for increasing about 30-40% treble to tone of this pedal

There's a couple of caps in that circuit with are limiting treble above 1.6KHz - that's fairly severe, although it's only a -6dB/oct roll-off.

The first is C7/100p. You could reduce that to 47p or 22p, to gain an extra octave (or two for 22p).

The second is C17/22n. You could reduce that to 10n or 4n7, again to get an extra octave or two.

Those two are where I'd start, anyway. There's plenty of "harsh treble" roll-off in that design, but one person's harsh treble is another's "presence", so try putting some of it back and see how you get on with it.

One other thing to note: Although the *frequency* effect of the two caps is the same, one is before the clipping diodes and the other is after, so they won't both have the same effect on the sound. You might find you like one very open, but the other much more closed, and that could be either way around. Just be sure to test it both ways.

off-topic, but..

I don't like C10 placement..
(at least, not without a 100R or so resistor - in the cost of IC2,2 output impedance..)

What about c19  (22n) cap in treble tone stack?
Do you think Decreasing it is beneficial or not?

It is 2,2 nF, not 22.   According to the diagram.
I would suggest increasing it a bit. 2-3 times.
And of course, reduce C17 to 1nF.

[antonis]

C19 is 2.2nF, if I'm right..

or better, use the following..

P.S.
Highs already attenuated upstream can't be recovered by altering C19 so make sure that LPFs corner frequencies already mentioned by ElectricDruid are above your highs taste..

Sorry, i was meant 2.2nf

You could turn up the treble on your amp....   

[Dormammu]

You could turn up the treble on your amp....   

Or turn down the bass and mids. Even on the box itself.

To do what on a signal of already severely attenuated treble..??

[Dormammu]

To do what on a signal of already severely attenuated treble..??

And where is the "severely attenuated treble"?
Are you saying that by throwing C19 into hell, we will not get any difference in the final signal?   
RC-filters don't work anymore?

I built the Angry Charles and I was also desappointed with the EQ.

Building the Captain Crunch Deluxe (MI Audio Super Crunch Box) solved the issue. EQ is much more effective on this build, and it's really easier to find some good settings.

I think Angry Charlie is a clone of the first version of MI Audio Crunch Box, with 3-bands EQ instead of a Tone control. The second Crunch Box version has its own 3-bands EQ and it's much better, in my experience. Probably the best MIAB circuit ever made. JHS's clone was interesting before MI Audio made the second version of their Crunch Box, I guess.

I'd suggest to  build the Captain Crunch Deluxe, and give your Angry Charles to a friend, you won't need it anymore.

Maybe in OP's ear..

Very strange statements.
I think you didn't appreciate active EQ because of your young age. (and lack of experience)
Passive EQs sounds flat for my taste, while active EQs provide some interesting possibilities.

Very strange statements.

Is it ? Reading the MI Audio's manual :

"a fully active 3 band EQ for surgical tonal precision"

https://miaudio.com/wp-content/uploads/2017/03/SCBv.2-Manual-2.pdf

They both have active EQ.

Despite my lack of experience and my young age, the Super Crunch box's 3-bands EQ has much more range than the JHS's clone.

If you are missing some highs on your build, you should probably try the original circuit.

Google search turned up not exact diagrams.
Ok, active — so active.
