edit 2:hi guys,
entrant: pink jimi photon
pedal name: photonic juergulator (yerg you later)first off, let me state that i may need to be disqualified, which i am totally cool with. i have been on the road 4-5
nites a week for the last 6 weeks or so, and with all the other stuff going on, have been as busy as a one legged man in
an ass kicking contest. so... despite wanting to submit a valid entry, i feel i may have hosed myself, and here's why.
i cannot submit the exact build/layout. the schematic is right, but at the time i built this circuit, i was dicking around trying
to squeeze it on to a 10x10 piece of veroboard, so it's a little different from the schematic... on the schematic, it shows
the "tweak" control as originally envisioned. unfortunately when i built this, i was out of 1m pots. the stock perc is
750k, escobedo's is 1m, so i made it in the original schem as a 500k pot with a 470k resistor on the collector side, and
a 47k resistor on the base side of q2. so i used two 500k's in series, which gets the job done. it could be built any
number of ways, the 1m pot lets you tweak it in a bit more, and should work well with the values in my schematic. but
again, DISQUALIFICATION fodder, on mine, it's preset.
(EDIT: FWIW, I HAVE THE TWEAK CONTROL PRESET AT 414k, which i found to be THE sweetest spot.. with my particular components.. that's what it's set at in the video i posted taken earlier today. don't do what i did, if you build this, do the 500k pot and resistors, it's worth being able to tweak...again, i did this only cuz i was out of 1meg pots.)i think the "percolate" control is cool. it changes the 91k/100k c-ground resistor of the pnp q1 to a 100k pot. on
the schematic, i made a mistake. oops. it should read 100k, not 50k.
anyways, the perc control is subtle, but lets you dial in the harmonics, and make 'em pop out some.
one more way disqualification may be necessary, is that i posted a demo of this mod, tho i didn't post the schematic
or layout or pics... just a SPTWPJP where you could hear the effect.anyways, i believe the percolator control affects the gain of the pnp, and the tweak (aka focus) control affects the gain
of the npn. nice simple addition, to me, it seems worthy.
totally can change the reaction of the perc circuit.
so anyways... some pron:



some gut shots






the obligatory schematic

the vero layout (again, this is slightly different from what i built)

the original video of the mod to the perc/jerk
and finally, the actual pedal put thru some paces.
so....anyways... if you need to disqualify, i totally understand. sorry to drop a problem in the judges laps!!!
just too many irons in the fire, and i kinda dropped the ball.
rock the f**k on!!

the vid/audeo is outta sync, too.....arrrrgh
who needs LSD?

please excuse the wankage. been one of them days, this was about the 5th try at getting video... i "updated" the built in cyberlink software in my laptop, and it went payware on me. so did the webcam "freeware"... i couldn't get audio apparently without paying them...arrrgh....
anyways... now... once i get a chance... i can finally enjoy all the other entrees. thanks to all who participated, especially the judges for making it happen!!
EDIT 3: too much coffee.....oooh, shiney!!!
