Do not change R8. Get as close as you can by selecting a JFET, then adjust R4 to dial in the bias.

You might find some J113s that will work. Look for some with Vp below 2V. As Brett said, plan on adjusting R4. MMBF4393 are readily available.

I collected this epiphytic cactus from the local botanical garden. They don't sell them, but anything that grows thru the fence is fair game. This is the first time it has bloomed.

SWEET!

Looks better than most boutique pedals. Just beautiful. And thanks for the kind words. Those of us doing mods on these forums are striving to achieve the tones that we like. When someone else appreciates it too, that's icing on the cake. Finally, hats off to the pedal builders who inspire...

Willikers!

I analyzed the filter in post #8 and found that I could replicate it using two resistors (R11 & R12) and two capacitors (C9 & C10) as shown below. The response is identical within ±0.5dB. While I was at it, I considered the problem of obtaining low-noise CD4069 (or CD4049 for that matter)...

It was just a crazy thing I tried and it worked! The DC voltage on the 47uF cap is much more stable with a MOSFET for Q2.

I'll get back to you tomorrow with comments. Yes, I know, it's already tomorrow where you are...

This circuit was inspired by T1redHands' contest entry. Loosely based on the Karma Suture, which in turn is based on the Harmonic Percolator. The main thing I did to be different was use a MOSFET for Q2. This could be built on a PedalPCB Antithesis board (omit R7). Mind the pinouts on the...

It's such a minor change that I chose to not roll the rev #. It was a judgement call.

Schematic has been corrected. (y)

😖

A minor update. Added R12 and rewired the PRESENCE pot. Ref des updated.

I might fiddle a capacitor value or two, but other than that, it's finished.

I still couldn't leave well enough alone. Gator expressed an interest in being able to control the mids. I tried a few different tone stacks and landed on a modified BMP tone network. My experimentation with the tone stack on the modded Hoof lead me to try it on the Gator OD and it seems to...

Here's the latest version. I used a MOSFET booster for the last stage and retuned the tone stack a little. This schematic is drawn for modding the Hoof board. If you're designing a new board, I'd make the SHIFT pot (VR3) A50K, wire it backwards (CW increases resistance) and label it MIDS...

It's easier just to use a BJT for the last stage. I'll provide a schematic in the fullness of time.

Yes, you could just leave R1A out and the the FAT switch would work fine. R1A is there to provide a little gain boost in TIGHT mode and it is also part of the EQ between the input jack & Q1. C1A attenuates a good portion of the bass & midrange, so I wanted to make up for some of the loss by...

30C (30% log taper) might be hard to find. Most audio-taper pots I see for sale are 15%, which will work just fine. For that matter, a linear pot will work there too.
