I guess that 150k resistor in the middle when the tone is bypassed helps to avoid all that volume bump.

Can I have the voltage of the Muzzle's ICs, please? I think on my build the transistors voltage have sense, while the IC TL072 and the THTAT combo no much. Ground -9v and 9v seems ok, but most of the other pins show voltage close to 0.00v. My PCB sounds, it seems work nice in the pedal chain...

I still have trouble with this PCB (I received a new PCB from Musikding, but not a new THAT chip! I still didn't ask why). I tested the circuit with the a Bogner amp of my friend, and it seems work better, or even fine, I could say. With my Laney LC50, instead, it gates noise and sound at the...

I noticed that in the video the pot change the voltage just in the first half. Is that an issue or is it normal?

Thank you. That's a good advice. Do you think the first stage of this schematic makes more or less the trick? (Though, I'm not sure that is real 1:1 buffer, but it's just to understand the thing). I hope we are helping the author of the thread, too. :)

Hi Feral Feline, could you post some schematics where an added transistor stage flips the phase starting something like the simple Split'n'Blend or Buff'n'Blend? I'd like to know something small to include in fuzz pedal. Thanks!

I was thinking about a project like that in these days. Do you prefer a Blend control or a separated Clean control? I think that a Blend passes from a total clean sound to a full fuzz sound. The Clean control just add in parallel the clean to the fuzz sound always on. Anyway, what about this...

I didn't write here, but this is a thing that Tremster should consider, indeed. I advice to increase a bit of bass at a time, until the effect is right for him.

Increase the input and output cap is a good trick, but these seems to me bigger enough. You can try to replace the 68nF with a 220nF, and the 1uF to 10uF, and see if you get more bass. Maybe you should try to increase even some coupling caps, like C4 (150nF) and C9 (220nF), trying bigger caps...

I meant, maybe we can use a 9v PSU and use a regulator voltage, like a 7805 to get 5v and supply the amp circuit. While we can supply the input buffer directly with the 9v getting more headroom and less distortion?

Cool! Is this sounds clean is very cool. Do you think we can use an internal board with a 7805 regulator voltage and supply it with a 9v psu?

Thank you! I contacted them and I'm waiting their answers.

I built the Muzzle with a kit by Musikding. What can I do now? Should I contact Musikding?

Hello, I built a few years ago the Muzzle for a friend. I was really impressed by it! After I built it I test it with my friend: I used its TU-2 to split the signal, used the Input key and put the pedal in the loop effect. The 4 cable method. I tried the distortion channel of the amp but even...

Ok, thanks. I read that technically are slightly different, maybe to adapt to the new chip the circuits should be slightly modified. This is what I get. But maybe, and I hope, the difference are imperceptible. https://www.profusionplc.com/images/data-sheets/4301-4305%20transition-guide.pdf

Hello, I ordered the Muzzle in kit from Musikding. I built it some years ago, but this time I got the three SMD chip 4305 adapter PCB. That's new for me. I have to start to populate the PCB, but I'm reading some issue with this adapter, and now I'm little bit worried. I'm not sure if I...

Maybe I can help you at least with the Graphite Distortion, I make a research just yesterday. You know that is the Mad Professor Grey Stone Distortion, right? Search the original version schematic, and to make the modern version you just add in parallel those three parts. - The 47nF cap in...

Very nice pedals and very nice pedalboard! How those illuminated knobs work?

I heard, sometime, about the squeal/whistle/oscillation problem in the Tyrian or more than else with a diy replica of the Revv G3 pedal using different board, like veroboard. Maybe protoboard not. I never built it, but I think that a signal track longer than G4 (Sanguine version), the mid boost...

That was referred right to the PAL800. Someone of us are trying to get the schematic of this new version.
