Cornerstone Gladio right side channel

[Drayve85]

I know we have the left side of the Gladio, the SC, but it would be awesome to have the right side, also! Maybe, possibly, could “we” take a Gladio dual channel (DC) and trace out the right side and put it into a separate box? After building the left side, I’m really interested in hearing the right side now.lol

It's a Zendrive. The left side is a Timmy.

Couple more points: the SC has the added clean blend circuit. The DC is really just a Zendrive + Timmy with the 4th knobs (Bass/Voice) respectively hidden inside the pedal as trim pots.

The comp switch on the Timmy side adds more clipping diodes, raising the headroom before the diodes clip and unfortunately letting through some nasty op amp clipping.

The Zendrive circuit has an internal switch to remove the soft clipping mosfets entirely, which sounds horrible. The Jazz/Rock switch is (IIRC) a cap to ground before the volume pot that does some heavier lowpassing.

The left side is a Timmy.

Asking purely out of curiosity: If the Scenario (Gladio SC) is a Timmy, and assuming that one of the ICs handles the clean blend, what are the other two additional ICs doing?

Pure speculation but I guess the rest of the circuit really is just an elaborate clean blend circuit and maybe input/output buffers and/or Vref buffer.

Maybe @Robert can chime in on that since the Build Docs are still coming soon?

Understood. Your claim "it's a Timmy" came across with certainty, hence me asking about the presence of three ICs not found in the Timmy circuit.

 

[jesuscrisp]

Well the Timmy part is pretty certain, what the rest of the ICs exactly do I don't know as I didn't have the SC version in my hands.

Regardless of what the right side ‘is’. It would be nice to have it, anyway. I mean how many Tubescreamers do we have?!?!lol

 

[jesuscrisp]

Just build a Zendrive...

 

[Drayve85]

I have already, a couple of them! But, they don’t sound like the videos of the Gladio. How do you know what the circuit is anyway??? Is there a schematic around or something? Or are you just going by what your ears tell you?

It's Timmy-like, yes.
The 4558 is the drive circuit. One TL072 is for input / output stages, one for blend, and one for VREF supplies.

As for the right side, the Jazz / Rock switch should be a dead giveaway.

A Dumbloid, perhaps?? Just a guess.
