DOD Looking Glass (circuit pics included)

[~nick~]

I bought 3.. it's a sickness. But I'd love to put this in a dual drive like a Duellist or a Gladio type pedal with potentially a lightspeed clone or a mostortion clone. This into a mostortion in one pedal. Imagine.

I took pics, but SMD parts are so tiny the labelling is miniscule if any at all. Is it possible to reverse the schematic? I know nothing about doing that but wonder if these pics will help PedalPCB make something. Here's to hoping!

One of the resistor spots looks like it's missing a component.
R12 is soldered, but there's nothing there! What gives?

Also, does anyone see any similarities between other pedalpcb projects? Looks like 3 transistor gain stages with two transistors in the clipping section. Correct me if I'm (most probably) wrong.

The structure could be traced from photos, but the SMD capacitors would need to be removed and measured out of circuit for an accurate schematic.

Makes sense. I do have a spare to share. Let me know! Why do you think there's a missing resistor?

+1 Big fan of this pedal

I'd certainly be interested in checking out.

I'm just guessing, but the missing resistor looks like it might be used to alter the taper of a pot.

I'd pair the DOD Looking Glass with a Fender Mirror Image delay and the Joyo Clean Glass Amp Sim. Or maybe something from Darkglass...

I see what you did there, and I raise you a Fender Reflecting Pool. This pedal is gonna be MASSIVE!! Massive Attack might even use it in their music, that's how massive. Anyway..

Should I DM you? Email? Would I get it back?

Do you have a utility pcb board where you can put two circuits in series A->B or B->A like the D and M drive? Add that to my wishlist.. lol. ^^

Shoot me a PM. I try not to break pedals, it'll come back home safely.

I am interested in this and hope it all works out enough to get a trace of it. I can’t remember if I played this pedal or heard it in a video... but it sounds great! ...and so shiny :0

Lots of reasons for unpopulated pads, most of which are intentional. Could be used as a test point in qc, remnant from a circuit revision and the board didn’t need to be updated, or a quick and dirty via.

Via con diodes, muchachos!

No way.. where'd you find this? Is that a board for purchase or a one off? Oh, the image file name says mockup, nevermind. Ya got me good.

 

[giovanni]

Never heard that one before. Sounds pretty good!

 

[Barry]

Well Andy sure makes it sound like I want one! Pretty versatile!

I'm pretty sure he would take the pedal you hate the most in the Universe and makes you want it anyway...
