Dirt Transmitter flings the filth

Postby noelgrassy » 17 Feb 2008, 20:23

Hi gang, I found something a little more my speed in terms of deciphering. This new [& discontinued] "fuzzdriver" from the creative folks at EarthQuaker Devices sent me #3 and it's huge in my single ended amp. Sorry the layout was done by my cloven hand but it is accurate to the best of my knowledge. Please, enjoy and offer any hints to the diodes part #'s. I provided 3 that I could see, that may be enough to ring a few bells in the EE types' vast data storehouses. Pedal>Image

The Value of R6 is wrong, compare it with the color of R9...
R6 is not 1M, it is 100k.

and the shown wiring is a liitle bit questionable/confusing.... sadly not photo of the wiring.....

One missing connection between C5 and collector of Q2
the connection between r4/r5 on the side of point (5) seems to be wrong.

From the topology it is basically a fuzzface-derivate.

Yes, brn-blk-blk-orange=100+000. R4 connects w/ lead #5. R5 connects w/ collector then over to the bottom of C5 to top of C4 to base[?] of Q1. That stuff gets me a little muddled where as it just glares at you, eh AG? Thankyou for taking the time to look my work over. I really triple checked it this time but I missed some elements again. Now let me revise the crappy artwork if the above changes seem plausible. Would you entertain a picture of the wiring? I'll give it a shot and post the results. :wink:

Anybody got this schematic kicking around? I sold mine a while ago and I miss it terribly.

I can't believe this pedal is 10 years old already.

Did anyone save the images from this thread? This circuit can't be too hard to trace; 2 Transistor FF topology.
Those 5-band Blue Resistors are super hard to read from the images online though.
