Re: Crowther Audio - Hot Cake Overdrive [traced]

you are checking for +9v (or whatever the supply voltage is after any diode drop/series resistance in the power supply) on pin 7, 0v on pin 4 and *very roughly* half supply on the both inputs and the output. You can post them here for analysis or search Google - Someone else is bound to have measure...

Jolt fuzz (a minor unpleasant surprise)

I really enjoyed messing about with Fairfield's unpleasant surprise circuit on the breadboard (or at least the schematic called the "calamity fuzz" that bugg has over at his pcb site), so I made a clone. If you haven't come across it before, it's a heavily gated and compressed aggro-fuzz, ...

Re: Crowther Audio - Hot Cake Overdrive [traced]

Ok. I don't want everything served to me on a platter, but as a beginner, how do i go about checking voltages in the circuit? Is there a good way.... use a multimeter set for dc voltage up to 20v, put the black/negative lead on circuit's ground and touch the red probe to the +9v supply rail (with t...

Re: BIGGER MUFF [documentation] [documentation]

Nice work, thanks for sharing the design. I periodically think I am bored with the BMP, have seen and tried every tweak, mod/extra feature and have exhausted the potential of the circuit, but someone always comes along soon enough with something else I just have to try out...... :shred: Weirdly, I d...

Re: Seppuku FX Mind Warp

I made this layout following the original pcb, the pics and the schematics that you guys posted. is it alright? Hello, and welcome to the forum. I had a go at bread-boarding this circuit using your layout and checking it against the schematic on page 1 (and please note i haven't compared to any of ...

Re: Mid-fi Clari(pirate)

OK, further to this - If you look at the "Doombutter (modified)" schematic over at madbean pedals forum, it appears to be a pretty much a clari(pirate), before doug actually released the midfi version. Here, seven of the eight controls on the official clari(pirate) are shown, with only the...

Re: Mid-fi Clari(pirate)

Weird isn't it? There's also only six controls listed on the midfi page, plus the square/triangle shape is mentioned in the text (which I assume is the job of the "wave" knob) but it has an 8th knob, just marked "LFO". I would have assumed this was for LFO depth.... hmmm. Not sur...

Re: Zvex - Seek Trem [traced]

every 4017-based circuit I have tried has had serious tick on the breadboard, I haven't ever progressed to boxing one up but I suspect this would improve matters somewhat.

I got good photos of the electronics, but I understand I should not post gut shots of Way Huge pedals on the forums... Why not? It is perfectly fine to do so. The proprietor of "the other stompbox forum" has (or had) some odd personal agreement with a few select builders not to host schem...

Crap, you're right. I think I'm just used to seeing that kind of bjt buffer with equal values voltage divider on the base and instinct took over.... now corrected.

Why would anyone do that? It literally doesn't control the volume without the ground connection :slap:

Re: Basic Audio - Lucky Number fuzz [traced]

I drawn a layout of this schematic, but I didn't build it and I'm not sure somebody else verified it. I redrew it from the pedalpcb schematic: You could check that one against mine to see if it's the same. Since bugg has already started selling boards for it, you can probably assume his schematic i...

{Q2 base-ground resistor value now corrected - see comment below}

The orientation of the electrolytic input cap looks odd to me. Nice sounding circuit, seems to be discontinued (at least, it's not up on the basic audio website pedal page).

However, the four diodes (and description on website of "dual clipping stages") suggests it's not just a TS clone with added bass control and mid shift switch.

The level potentiometer is not grounded, but it should be in order to function.
Deafeningly, uncontrollably loud without lug1 of the volume pot to ground: Family and neighbours can affirm.
