Chunk Systems - Brown Dog Fuzz

Post by **rcubed** » 29 Mar 2009, 16:12

I did a search and didn't see anything on this gated bass fuzz pedal. Anyone have a schematic of it?

Here's the effect in question: http://www.chunksystems.com/bd.htm

Thanks!

No one?

I'm also interested in schem or gutshots of anything from Chunk Systems : Brown Dog, Agent 00Funk Mk1 & Mk2, or the new Octavius Squeezer (just dreaming for the last one ...)

A friend of mine has one; I'll try to get him to borrow it to me

That would be great!

There are some gutshots here but not enough to trace out the circuit: http://bassfuzz.com/2009/04/02/fuzz-rev ... ss-fuzz/5/

Looks to me like a moded Red Llama or a moded Big muff depending on the ic because i only see one ic its either a LM3046 ie(Big Muff) or 4069UBE ie(Red Llama), I also could be completely wrong in which case im a dumb ass

Looking at the traces on the back, it doesn't look to be that complicated of a circuit. I don't see any diodes so it's probably not any sort of Big Muff-like circuit. I can see the IC (two op-amps?) and FET or BJT transistor. Not a whole lot of caps and the ones I see are electrolytics.

Maybe i'ts just my imagination, buy after some image manipulations i read "TL074CN" on the chip.
If it's not an opamp BigMuff (because of the lack of (visible) diodes), it might well be something original ...

It's got 14 pins so it's not a 4049 anyway.

is it at all possible that the diodes are on the pot board ..... it just seems weird , an op-amp fuzz without diodes, maybe it uses mosfet for clipping

A bit strange, isn't it? Hopefully Bernardduur can come through with some better gutshots.

Shame; he had the Brown Dog for a while but sold it. He still got the Agent 00FUNK which I took apart and placed on the forum. He misses his unit though so I think it'll be added to his rig pretty soon.......

(well, I hope so

I dun used'ed the search'm tool.

Perhaps its just a modded brown source with a noise gate of some kind?

I have one -- the early (and best) version that is slightly larger and more tweakable than the later or current production. I won't have time until the weekend to take it apart and give you guys some gut shots.

I bought it because it sounded just as good as the Lovetone Meatball, and is easier to use as well, not to mention much smaller.

Desperately wanting more gut shots and a possible schema bumpy bumpy bump.
