Suhr Riot Clone Mod Help

Hey fellow shredders...I have a special project in mind! I have a clone of a Suhr Riot and it rocks but I have recently fell in love with "fuzz" in some of my playing and don't want to add any more pedals so I was wondering if there was a way to modify the circuitry to the Riot board to get the "fuzz" I want. I'm good at soldering and have some knowledge of basic parts. Thanks for any help.

It's not that it's "top secret", it's that there are only a couple of GB&C regulars left and we don't post often.

I found this, hope it helps. I know nothing about this pedal, sorry.

Hey...thanks a bunch!! I hope I didn't mean sarcastic to the community...I was trying to be a little humorous. I suppose I could use that schematic and maybe get a schematic of the "Big Muff" and figure out how to merge the "fuzz" components in on my board....I just have to find someone who knows what components make the "fuzz" happen...lol.

Again, thanks for responding.

Hey, the old fuzz boxes were far simpler than the riot is, I think it would be easier making one from scratch than modding the riot! Why don't you want another pedal again?

I knew you were being humorous, I was just saying that this forum is pretty dead most of the time. No harm done.

Anyway I took a look at the diagram (couldn't the other day because we didn't have Wi-Fi set up yet) and all Tue clipping is done by the diodes and LEDs around the switch (or is it a relay?).

You could mess with those but it won't affect the gain very much, only the timbre and amount of clipping. Lots of info online about the tone of various types of diode clippers.

To mess with the gain of the circuit, the negative-feedback loop of u1b and also of u2a can be tweaked. Lots of info about that online too.

I don't want to add another pedal because I like to keep my stuff simple and very mobile...The Riot just has a kick-ass sound to it though...I mean I could just buy a Muff and add some punch to it but the Riot has a really killer tone...

Ahh...great information! I'll definitely check it out now that I have a starting point..
