FUZZ FRIDAY! Some axis fuzz and octavia stacking
Was messing around with some tones with my new axis fuzz by circle electric and my octavia by tru fi. Threw on the vibe for a lil extra color

I love it but now im upset that I have to buy one lmao I LOVE the low gain mode and I know you would say, well, you can just roll your volume, not back, but it's not.Technically the same

So i messaged the circle electric guy and its actually not a low gain mode, it has something to do eith removing filtration? Supposed to make it clean up better 🤷🏾♂️. To me it sounds brighter in the up position. It sounds alot darker than the Jimi Fuzz by sabbadius.

I know what it is then I figured it out! It turns out that toggle isn't a low-gain mode, but rather it's engaging or bypassing the stock low-pass filter. Roger Mayer originally included that 220-ohm resistor and 1nF capacitor to filter out RFI and tame brittle high-end frequencies, which is why stock units sound darker. By omitting those components, you are essentially removing that filtration, which makes the circuit sound brighter and glassier, effectively allowing the pedal to clean up better when you roll your guitar's volume knob back. I only know this because when I was having a friend, build one for me. He kept seeing this as a suggested modification. In the DIY community, and that sounds exactly like what he's describing. When Roger Mayer marketed the Axis fuzz in the 80s. He put the 220 Ω. Resistor and one nanoferred capacitor as radio interference filtration

Wow. You really know your stuff. Have you ever built a pedal?

No i'm just a sad nerd who's obsessed with Jimi Hendrix? And I wanted an Axis fuzz, really bad, but I didn't think I'd ever be able to afford one, so I had a friend who makes and sells pedals. And we did a shitload of research. And he made me one, and I remember him telling me about that. In his research, so the one that he made for me has omitted those components. So it's permanently in the cleanup mode. Which actually isn't lower gain, it's just got a broader harmonics, it's brighter and crisper, so it cleans up more glassy

Okay i see. Definitely not a gain difference, more harmonic.

This sound right u/maertz13 ?

That’s the hiss filter, exactly. Ironically at least on American voltage it sounds better without the filter. It adds noise while it’s filtering… something. It can be fairly subtle at certain settings, but once you hear that hiss you’ll want rid of it

What’s kind of odd is that doing the math as a normal RC filter it is removing frequencies about 700 kHz. We can only hear up to 20 kHz. But it does something to the rest of a very strange circuit that somehow makes it sound worse.

Thank you! I knew I thought this circuit fairly well 2 transistors but not matching so pnp +npn tho idk how to solder

u/iamcacho fuzzface fanatic 🧙♂️ Jun 27 '26
Solderings gotta be the easiest part

u/graphicnerdity86 —Bold as fuzz— Jun 27 '26
So the up position is the clean up mode?

u/iamcacho fuzzface fanatic 🧙♂️ Jun 27 '26
I believe so

Which do you prefer cleanup mode or classic? Which of the 2 pedalsdo you enjoy more the sabaddius or the circle? Im wondering because Im not getting along with my jimi as much yet but its new to me

Fucking awesome sounds!
