I’ve built it. It’s cool. But that unfortunately didn’t lead to me understanding this hard clipping arrangement. The resistor and cap, what are they doing? I’ve never seen this before.

This can be mitigated by scaling the filter in the feedback loop. 560r and 4u7 can become 5.6k and 470nf, keeping the filter the same but lowering the gain. I actually do this to both filters and then use a 250k gain pot. All the “way too much” of the original, and now a low gain setting.

Working on a PWM style bass synth thing and I can’t seem to get enough clean boost into the input of the 40106 for it to register. If I crush it with distortion, it gets loud enough, but it’s messy. Currently I’ve got the amz my amp driving a 386 with 1 and 8 jumped and it is working, but it’s...

Volts DC

it is connected to the collector of Q2

ohhhh gotcha. it's worth noting that the bias control only affects Q2. any other drifting due to temperature inherent to germanium is just part of the charm. roses and their respective thorns.

Need? I guess technically never. But man is it a lot of fun. Changes the mids, changes the texture.

i've got a cheap orbital sander. i hit it with 60 grit first, then 220. if i'm painting, i'll just clean it up with some steel wool and then alcohol. if i'm keeping it metal, i'll wet sand with 400, 800, and polish with steel wool. i can't get the perfect mirror finish, but i'm also working out...

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
