Yeah I got the bum deal
What you can't see in this picture is all the fucking rust and acid shit all over the pots. Nice!
I console myself by looking at the enclosure. So, when do we get the t-shirts made?

That sucks! Ya know what though? if you made a couple or ten or so you could keep the best one for yourself and sell off the runts to the crowds waiting in the wings... and then do a run of commemerative t-shirts!

hey captain, that sucks!! it looked like mine had been cleaned up, and some cardboard put in for insulation. the pots on mine are fairly gunked up too.
got a workalike up just now, but haven't got set up with jacks etc... to try a guitar. on the scope they look pretty much alike. the copy first and the original last.

Re: Earth Sound Research - Graphic Fuzz (Data Dump)
Ah, I didn't get that honour Just gone at it now with a toothbrush and I'm getting sounds....crazy loud sounds!! The battery blow out has seriously fucked up the pots, especially the Filter so I might have to pull those to get it rolling proper. Sure is one crazy sounding bastard so farjerms wrote:hey captain, that sucks!! it looked like mine had been cleaned up...

pots: filter 1M, level 10K. all caps .1@10v. quite a strange design, i'll try to get a schemo up tonight.

yeah, as i turned up the filter and the tone came in, turning the tone knob will find the sweet spot and cancel the tone out.

Re: Earth Sound Research - Graphic Fuzz (Data Dump)
hey foxfire, it's a pretty odd circuit isn't it? the filter control connects across the input and output. and the - battery terminal doesn't connect to ground just the #4 pin on the IC and a .1mf/10K pair. the input jack has a completely isolated switch to connect the - battery terminal to the circuit. pretty weird

Re: Earth Sound Research - Graphic Fuzz (Data Dump)
that and no in/out caps. maybe it's so odd because it's the BEST sounding pedal ever? but that's just hte pot in me talking.
