Danelectro - CO-2 Cool Cat Drive (V2)

I bought one of these a while back. I haven't had a lot of time to play with it, but it's a nice little overdrive/distortion pedal. The V2 was introduced after the hubbub over it being an OCD clone (although there was a lot more hubbub over the Transparent Overdrive - no one cares that much about Mike Fuller, apparently ).
I opened it up last night and just had a quick peak. The opamp is an LF353, a JFET amplifier similar to a TL072, apparently. No clipping diodes were immediately apparent. Inside there's a trim pot for a gain and a "lo-fi" dip switch. I didn't have time get pics, but I'll try to get some in the next day or two or three.

And how does it sound ?sch929 wrote:Out of curiosity, any updated?

Sounds pretty good. I haven't attempted to draw a schematic or do any mods to the pedal. I just thought people might want to see the gut shots on this thing, due to the revision and internet scandal and all that.

Just one - a lo-fi switch. There should be a pic of it in there.DWBH wrote:No DIP switches?
Edit: it's the last pic
...any news of the circuit? does anybody know the changes?

I really like this pedal and I'm trying to figure out if it is a clone or a modded clone of a higher end pedal. I don't really buy the hype that it's a mod of the V1 or an OCD because they sound so different. The V2 can get into fuzz territory and despite all my best efforts I cannot get a V1 or OCD even close to fuzzing out. Ultimately I'd like to find or build a higher quality version because I've had 2 of these break on me. I can get it rehoused but at this point I'm more interested in the pedals origins. It' s also curious to me that the guts of my CO-2 pedal look rather different from the one pictured. Any help would be greatly appreciated.

The topology would be easy with a perpendicular photo of both sides even if you didn't get the values from it.

Crikey, is that stock or modded?
Anyway you should be able to trace that; crank the contrast in paint, so that you can see what joins where, and then turn that into a schematic; use google for the std. dual op-amp pinout.

So I have 2 of these pedals. I bought one as a back-up after I had a CTO-1 fail on me. After looking at the first set of pictures in the thread and noting that the board says CO-2 I wanted to find out if the boards in both of mine were identical. They are not. The first one I purchased is identical to the first set of pictures; the 2nd/"back up" is represented in the pictures I uploaded. I guess it could be a revision. The older one has more mids and significantly less treble and sounds better IMO.

The tacked on through hole capacitor must be a factory mod.

Information
he meant- use google for the standard dual op amp pinout. so you know where the ins and outs are on the chip.jonny4rd wrote:Not modded.
I have never created a schematic and don't really know the appropriate symbols for everything but i will give it a shot. What did you mean when you said "use google for the std."?
funny how noone gives a shit about this pedal anymore after the initial storm over v1. personally, I'd like to know if this is really an original design or not.

Iam rehousing on of these right now. It looks identical to the one pictured.
