Did you build the Friedman BE-OD with a PedalPCB board?
I heard it's a bit noisier than other high gain pedals. Actually, it was a veroboard layout, maybe that makes some difference.

Any news about the schematic of this pedal?

Thank you, Manfred. You're right, that layout was my old version, indeed I corrected those mistake just like you said. Here my layout: https://i.imgur.com/yNI1lg7.png I didn't try Lochmaster 4.0, I don't like too much how the layout is drawn, but the highlight function can be useful. I guess I never...

Excuse me, but how a Tube Screamer sounds so distorted, and using LEDs for clipping?
Ok, I see the Drive pot is 1M, the gain resistor in the VREF is not a 4.7k but 1k, and the cap is bigger (470nF), too. But this pedal sounds like a distortion.

[...] I'll see if I can locate my build, but my recollection was that it was not as "buzzy" as the original DS-1 but more of a mid-range distortion. Yes, more mid-range it was I meant. I never tried directly, just heard some demo, but I like the DS-1 with mosfet clipping. I don't remember any pedal...

Thank you!
I'd like the idea of this circuit, but I don't know if I'm going to build it so soon.
Does it sound close the DS-1? I just see that eq is difference and not scooped like the original DS-1. No demo anywhere, I guess.

Old post thread but, Frank_NH, did you never share your layout?

Yes, I got it, highlifefin.

Thank you Nocentelli. I tried with the emulator software to change the cap I see in the schematic you posted. The range is pretty wide, but maybe trying this mod somebody could find it useful. I'll keep to experiment with it.

Is there some easy trick to get a scooped mode option? With a baxandall, with both treble and bass controls at maximum (and the volume reduced a little) you will get a mid "scoop"; both controls at minimum (and a little more volume) should sound like a mid "boost". In both scenarios, the mids level...

I soldered pots directly through the wires, avoiding excessive length. Sometime the layout makes the difference in the oscillation issues in high gain circuits. I built twice on veroboard a multi clipping Rat without any problem. Then I built a stock and smaller version getting oscillation in some s...

There's just a missing value one it: R15. Maybe 82R.
I emulated that schematic. It doesn't have the mid scoop because it was in the classic Big Muff tone control.

Hi Bajaman.. thanks for this circuit! I Just finished build the true bypass version of this, using slightly modified layout from dirtboxlayout to accomodate latest schematic.. circuit was quiet, not as noisy as ripthorn smd version.. ballsy with tons of gain and low end for chuggy chuggy.. but I go...

Ok. Thanks, I got the story.

Can we have a "working" version of the schematic, please?

So, in the end that is really that the correct schematic?
I tried to emulate it with the software, but I got low signal and an important cut of bass and very large treble roll off.
The trimmer doesn't help much. Should it carry 4.5v at the J201 drain?

Do someone know something about the four knobs version? It has a Clean control, a sort of blend.

Thanks for sharing it, UncappedOptics.

I guess the Bass pot is reversed.

The schematic is in the doc, now:

I tried to draw a layout.
NOT VERIFIED



Warning: Two cut track even under the transparent 18nF.

Tell me if you see something wrong.
(Probably I can't build it soon.)

Hello. I started from a Crunch Box veroboard layout to convert it in the JHS AT version. Almost the same thing, I just used an external pot fot trimmer to have the Air pot and a 100nF in the power supply. ANd I added 1k resistor before the lug 1 of the Gain pot. The EQ pot is a reverse log, followin...

Great update! I got one odd thing. I have a 1 next the Private Message button, but I have no new message. My last one was in April. I means that there is a message that (technically) hasn't been read yet... it should show in RED. There is another bug in the message system: when selecting multiple m...
