Noise + high gain = higher noise...

If you look at the schematic, the fuzz control is merely a gain control for the last op amp stage before the output. It relies merely on clipping that op amp which means it'll boost the volume like crazy before going into an ugly distortion. Also the dry path for some reason is crazy dark sounding.

That's because it's a really stupid design since death by audio are total hacks when it comes to circuit design.

Just in time for the end of Black Friday. 🫠

Yes. 9V bipolar is 18V

You won't gain anything from trying to hack on another charge pump. The power supply of the VH4 pedal is a stupid design really. If you want to run it more effectivel from 9V, just don't install the regulator, jumper its in and output and it will run at around 18V internally.

Your main issue will be misbiasing as you'll have resistors and pots on either end of the op amp going to ground (on the input only if you put another pedal in that lool) but your inverter is biased to virtual ground.

Oh you will totally have issues without coupling caps around the inverting stage...

In short: no

depends which 50%...

I'll write it myself ;)

Can I have an untested one for 50% off though? 🤫

What am I looking at though?

While this MIGHT help I'd go ahead and simulate it. With these types of tonestacks you might end up just setting the cutoff frequency lower which may counterintuitively result in even less perceived changes to the low end and more mid scoop.

Are you sure about all your pot values and tapers?

No need to add another 2 buffers to a build that already has input and output buffers... Add a capacitor into lug 3 of a 100K pot here: ... and connect a cap from lug 2 here: Lug 1 goes to ground. ALTERNATIVELY, you can make a "faux EQ blend" by replacing R29 here with a pot, e.g. A5K...

This one might sound horrible with the buffer up front I'm afraid, also not sure how much sense it makes AND you'd definitely need to flip the phase back on the clean part. I'd rather just do a treble booster with the range and maybe a tone control and the heat/gain externally so you can vary...

Are they really that different before you put the knobs on though? If the knob is sitting too low, it can cause the stiffness. Always slightly raise them away from the enclosure before screwing them tight.

Why choose the LM358 which is hardly if ever used in pedals for anything else than LFO if I may ask? Also disagree that it isn't great for high gain, depending on what sort of high gain you're after. Other than some of its nasty crossover clipping behavior, I thought it sounds great for sludgy...

Do you say that because you actually have a real LM308 that you could compare it to or because you watched some clips?
