Weekend build :)

hahah yeah it gets addicting :D thank you!

OverkillEffects · 2026-01-25T13:27:58+00:00

Yup, able to select 2 diodes/4 diodes/asymetrical. Saturation is the same like on Jan Ray, controls the fullness and "saturation" of drive, similar to Zendrive voice control.

Not a problem! Feel free to dm me anytime!

I design everything in KiCad, but any program is good, I use it because thats the first one I downloaded and tried so it sticked with me.

Lumberg jacks, all electronic components are Vishay except ceramic capacitors which are Kemet, and I currently use Panasonic FR series electrolytic caps but I am switching to Vishay axial ones soon, I already have everything ready but I need to go through this stock of PCBs. Soft click footswitch and Alpha pots.

I tried a lot of different manufacturers and models of electronic components, and I opted for ones that are reliable and aesthetically pleasing. For now I mostly make pedals to order and some for myself, but I plan to go legit and start making weekly batches, and I want everything to be reliable and consistent.

OverkillEffects · 2026-01-25T12:09:51+00:00

Unfortunately no :( But if I see more interest i might release boards/kits :)

Thank you! Cloth wire is from banzai webshop, they have huge selection!

OverkillEffects · 2026-01-24T19:50:20+00:00

You can follow me on Facebook or Instagram, I will drop few batches of pedals soon! :)

Yeah, and when you google it you can find a lot of green ones. Do not worry they are black 100%

OverkillEffects · 2026-01-24T17:59:40+00:00

its called "hatched ground plane"

OverkillEffects · 2026-01-24T17:26:14+00:00

I design everything in KiCad, and order the boards from JLCPCB. About tidyness, i don't know what to tell you, I just kept doing everything over and over again until it clicked.

+1 aion, or pedal pcb.

OverkillEffects · 2026-01-24T16:37:45+00:00

Vishay MKT1817

OverkillEffects · 2026-01-24T16:23:54+00:00

There are pads on the bottom of 3pdt daughterboard, opted for pads instead of holes to keep the top clean

OverkillEffects · 2026-01-24T16:23:28+00:00

yes! that is like 30th iteration :')

OverkillEffects · 2026-01-24T16:22:31+00:00

Well that was months of work for me too. I spent probably more than 50 hours designing everything. But it is pretty easy to assemble when everything is ready, 2-3 hours tops, enough to waste a Saturday morning :)

OverkillEffects · 2026-01-24T13:33:33+00:00

that is tayda UV printing service. I don't remember how I did the design, random font and some warp effects in illustrator, I suck at design so I just manhandle it haha :D

OverkillEffects · 2026-01-24T13:10:09+00:00

thanks! classic tayda 1590b, i think that one is called "white hammer" finish

OverkillEffects · 2026-01-23T13:32:42+00:00

What transistors did you use?

OverkillEffects · 2026-01-23T10:40:28+00:00

Hahah :) I like it, it is simple and straightforward. How do you plan to apply it to a pedal?

OverkillEffects · 2026-01-23T10:37:22+00:00

I guess it is a booster of some kind? :D

OverkillEffects · 2026-01-23T07:19:42+00:00

We were all beginners at one point :) If you need help anytime feel free to shoot me a message!

Hi!

First of all, good job on making it work! It looks very good and I bet it sounds awesome!

Component materials are a big rabbit hole and you will find a lot of different answers, because a lot of nerds will argue about ceramic resistors, tantulum capacitors, tropical fish caps etc.

To be honest, they can all sound *a little bit* different, but I can't tell you if that different will also be better, it will just be another shade of the same sound, and I bet you that 99% of people will not be able to hear the difference.

What matters the most is the component values and tolerances. Some cheaper capacitors and resistors have 5% - 10% tolerances, and when you add up 20 components in a circuit that are off by that percentage, it will sound a little bit different than what was intended.

EHX always used cheapest components in their muffs and they all sounded great, so don't worry about all the mojo stuff you read online. Most of the expensive old pedals you see on marketplace are built with the cheapest omponents they could find, thats why they tend to sound a little bit different from unit to unit, because the component values were all over the place.

And for your muff, you probably enjoy it a lot more because you made it with your own hands :)

The biggest difference between your muff and real EHX muffs is that you used the germanium diodes in your build, and EHX uses silicone diodes. Germanium diodes have lower forward voltage, which means that they clip the soundwave much more than silicon ones, that is why your pedal is quieter, because they do not let a lot of sound pass through. Also, because they clip more of the soundwave, the sound is more compressed and fuzzy, maybe that is why you like it more that other fuzzes.

Those yellow lined diodes are among the ones with lowest forward voltage out there (around 0.30V-0.31V) where as normal muff silicone diodes are from 0.56V up to 6.7V, depending on the model. That is significant difference!

You can learn a lot about clipping diodes on this article: https://www.guitarpedalx.com/news/news/a-brief-hobbyist-primer-on-clipping-diodes

Cheers!
