Crunch'd Box Finished!!! (working)

[vendettav]

Yey finished breadboarding a crunch box clone and it works like butter

used this schematic

the only thing that I changed is the C2 which I couldn't find and put a 0.0068 (the closest I could get to 0.001) and I took of the tone knob out..
so lug 3 is connected directly to lug 1. lug 2 and C10 are not there (did this due the lack of room in the enclosure)

anyways i have a few questions/plans... with my strat it was kinda bassy you know.. not that very crunchy so i am thinking of boosting some highs in the end.... or a bass roll off... basically something to brighten it up. also may be a i could put a fixed mid scoop?? ideas?? how do i do this??

and yeah it's freaking cool!!.. really awesome.. i'll soon put this on a prefboard and into an enclosure
i'll put up clips along with pictures later when im done

 Can you tell me what leds did you use for D2 and D3? Standard red 5mm will work, or do i need low currents?

I don't know what  C2 to ground does, but you made it over 6 times larger, so I wouldn't mod anything yet till you try the real value.

It's a cliche, but lower the input cap C1 to brighten it up.

good luck

The tone section is important. Especially, try finding the schematic for the version with a presence knob. It makes a big difference.  I'm not sure what you mean by "crunch", but I built this box to get some nice chug chug metal sounds and it's all about the EQ after the high gain.. I tried a few different tone stacks (Big Muff, SWTC) before settling with the Crunch Box's tone+presence one.

Basically the 10K / 4.7K divider at the end is replaced by a 20K pot (I used a 25K because that's all I had).  220nF for both the tone cap and the presence cap. The 1K becomes 470 ohm right before the clipping LEDs.  I think that's pretty much it.
