has anyone opened one of these up and seen what makes it tick? i had someone ask if i could replicate it since they are always out of stock, and i can't find anything. the cmos hex inverter thing is WAY over my head https://www.broughtonaudio.com/product-page/synth-voice-deluxe

The last few months I have been on an intense deep dive with the Fuzz Face topology. I have made what I consider to be the best possible Si FF's in varying gain ranges, I've made them 1590L sized, I've considered anything that the end user could possibly want or need. This all stemmed from a...

worked like a charm. thanks bud, you're a life saver. and indeed the switch-bastard. a good idea is only good if someone helps you implement it ;) rate LED is a solid use case for this. hadn't even crossed my mind. i've previously put a mini toggle to turn it on and off with the pedal. a...

thanks @Feral Feline , i'll give that a crack when i wake up tomorrow afternoon and report back. i've got both common anode and cathode. i hadn't tried *2* CLRs, only tried stacking them. i KNEW it was easier than i was making it

I was fighting for my life trying to come up with a thread title for that, hope it isn’t too confusing I have built a fuzz face with a regular bypass footswitch on a 4pdt and a pre-gain control that is bypassed by a 3pdt footswitch. The pre-gain/ channel switch has a 2 color LED to indicate...

Suppose it’s also worth mentioning that I’d be building this on Vero. Makes a lot of this easier logistically.

It’s 100% op amp driven

plotting a power amp build and want to put an EQ and volume control out front. basically a take on a SD powerstage. The power amp module has a built in PSU and an auxilery bipolar 12v output. I've heard people say that running an op amp circuit off of ±V instead of +V/VREF is an easy mod, but I...

but then they had to unhook everything and unscrew the battery door on the bottom when they DID expire :p

there are bypass footswitches for both effects as well as a toggle switch to turn off the battery. it breaks the negative connection so the battery doesn't die. i guess they hadn't worked out switching jacks yet

in the event that i disconnect that battery switch and take both grounds to the negative pin on the DC jack, think the issue would just go away? because that's the end-goal. get both circuits to work on a single 9v supply, add a protection diode, maybe a small dropper resistor to simulate a C-Zi...

if they weren't working at all, I'd expect it to not work with batteries, but it does

yes, polarized. negative end of the caps go to the battery disconnect switch/negative battery terminal

alright braintrust, here's a fun one. I was sent a vintage Rosac to check out/repair/mod so that it is no longer powered by 2 separate 9v batteries. It works fine on a battery, he said, but a voodoo lab power supply to battery snap adapter made terrible noise. those were my findings exactly...

that is exactly the kind of quick and dirty solution i was looking for. i guess it's a modern take on the anderton schematic i saw but it didn't look complete. this with a fixed volume and a DPDT bypass switch will be perfect

yes, the original pedal is fairly scooped already

Hello all, I’m looking to add a mod boost eq to the front of an existing circuit. I know the Clapton mid boost exists, but it is huge. Hoping for something op amp based. Just need to be able to switch in some mids to goose the front end. The zorkmid has this sort of boost, but the build doc...

swapped out Q1 and Q2 with 5457's an biased everything to 10v (at 18v input) and got some pretty solid results. the low gain section of the pot is still tiny, but it at least exists now. might try the rest as an experiment later

howdy just built up the boogie monster running at 18v, biased all nice, and it sounds great for the heavy rock and metal stuff. all the rectum frier tones i could ever want. but even at A1M, seemingly the most subtle of all pot tapers, the gain knob is like a switch. almost no sound to BAM as...
