Kliche Mini - Which Capacitors Affect Tone?

[DailyDovetails]

The Electrosmash article https://www.electrosmash.com/klon-centaur-analysis has some good stuff about this. If you look at the gain calculation section it shows that there is a mid peak that develops as the gain is increased. It looks like it shifts from 500hz to about 1khz as the gain is increased. My guess for making it warmer would be that you want to broaden out the peak and possibly add a bit of bass in. A touch of 100-500 is typically what I think of as warm.

This is exactly what I want. Any idea how to go about doing that? I haven’t read the article yet, so if it is all in there, my apologies. I plan to look through it later.

i think the filtering on this pedal is fairly interactive with itself. That being said I think what you are looking for is to adjust the range of one or multiple high pass filters and that will open up that range some. I think it might be kind of hard to do by taking random stabs at it. You may get lucky tho.

If you modeled the circuit and did a frequency response it would probably be easier to figure out. https://www.falstad.com/afilter/ Is the easiest I have tried.

I strongly recommend building or at least breadboarding Chuck D Bones bass version

So, tonight I started building out another one with sockets so I won’t have to breadboard the whole thing. This will allow me to try Chuck’s substitutions but also allow me to experiment and maybe stumble upon a version I like.

I'm a firm believer in this method of circuit exploration.

Well you got my mind going on this circuit. I think the gain 1 and 2 might not work correctly as the diodes aren't modeled but it should give a good idea of part changes and how the effect the EQ curve. https://www.falstad.com/afilter/cir...+4.5+0.1 o+0+16+0+34+5+0.00009765625+0+-1+in

Well, here is where I landed with substitutions. I’ve added the values in with a pen and a red ink dot to show where it is located on the board. I like this result, but might try other amps and guitars before calling it final.

I’m open to feedback if you have any thoughts. Some of the values are drastically different from the original spec, like the 15k ~ 470k. I like the sound though. A bit warmer but still enough bite to cut through. I don’t have a spectrum analyzer to validate or verify this but to my ears it smoothed out the 1kHz frequency peak just enough to get rid of the “honk”. (Or at least it added enough of the other frequencies around it to make it seem that way.)
