"'O', this adjusts the amount of overdrive. As you turn up the knob, wave shaping is applied. This wave shaping was inspired by 1940s analog computer technology ..."

Huh?

sounds pretty damn good (for a vid clip) wonder what the hell they have going on in there?

I just watched the video... jeesh...
Well, one thing I can say with almost absolute certainty is that the "D" control is a variable resistor in series with some diode clippers to ground. Seems like pretty standard stuff....

That's what he wants you to think....

I have one on the way... Will post some guts.

just watch some clips of this pedal... very interesting

Okay, now we've gone off the deep end.

I'm snipping the off-topic stuff and moving it to the Member's Corner.

Please feel free to continue this discussion in the new thread. This stuff just is not germane to the topic at hand.

Carry on.

i would like to see the schematics of this one,
any idea what type of circuits is inside?

Probably some CMOS hex inverters or gates. The old Craig Anderton tube sound fuzz.

But I have no idea what they are doing. The Redeemer buffer circuit is actually kind of involved, judging from the patent application.

and it comes with 48VDC power supply

Where are the guts??

There's your quick explanation of controls. I find it very interesting that the indicator changes from yellow to red if you're pushing the pedal's input too hard. This thing is pretty wild!

I agree with Güero 2.0 though... where's the guts?

do you have a link to the patent app?

gain, overdrive, distortion... don't those all generally mean the same thing?

This is the signal path through this thing:
Input -> OD -> Distortion -> High Cut -> Gain -> Output

I'd think of it as a box containing a tube-like preamp, a tubescreamer, a very basic tone control, and a volume circuit in series.

Gain = Volume on this pedal. Unity seems to fall at about 11:30 in the clips I've seen. Adds up to 12db to your output. Their user guide states that this should be seen as an overall volume knob.
Overdrive = The drive you push the distorted signal into the gain circuit with. I'd think of this like a preamp, because it's their "wave shaping" circuitry. It's supposed to shape the wave exactly like what you get when you push a tube amp into OD.
Distortion = Adjusts the amount of clipping you get. It applies a "squaring" to the wave signal after about the 2 o'clock position per their user guide. I'd think of this like a Gain knob.
Hi-Cut = A treble cut of 3db from 20kHz down to 500kHz.

some photos, not too clear though, and it's SMD

? Suitable for use on Phantom Power maybe?

The poster on DIYSB says there is space for 2 X 9v batteries inside the case which tends to suggest that the circuit does not need 48v. With opamps 30v (+/- 15) is the usual safe max although I seem to recall using some with a working voltage of +/- 18v many years ago.
