Pink Jimi Photon's Transmission OD

Incorporating couple of cool ideas, here' one from the man, Pink Jimi Photon. Note that the master volume control is optional and anything smaller than 1M will probably hurt the output level. The level should be within reasonable limits without it.
Here's the original description:
Positive it's been done a gazillion times before. but one little twist... i added a simple control to be able to "pan" between the two clippers... one made with 1n4001's (slower clipping for the lows) and one with 1n4148's (faster clipping for the highs)... it works, kinda sorta.. it's more noticeable at some settings than others, it's mostly useful for dialing in "touch sensitivity"..
the tone control is what it is, fairly simple and crude... but for one freekin' transistor, it actually works pretty well!! at least i think it does..
i didn't put a master volume on it. you just crank up the gain to where ya want it. unity gain is about 8:00, above that it just kinda gets more saturated (and a bit louder)...

how does it sound? kinda like a tube screamer. ::) which wasn't what i really expected at all... it's a kinda nasal middy overdrive, cleanish, but enough to bump an amp into a really nice natural overdrive sound.

  1. Two connections to Shift 1, or is one of those supposed to be Shift 3?

  2. That would make more sense.

    2. ;)

      i gotta couple new things in the works, will post shortly...
      did you see the fuzzy goodness overdriver yet?

      three stages of ge goodness, took the fuzz from a maestro rhythm and sound, f'd with it a bit so it would run on 9v and then played with the voicing... it's actually pretty hip, i think. this one and that together sound really good... if ya need a schemo to look at, let me know, miro...
      peace out!!

  5. what the 500k trimpot does? nice sound! nice work pink!

  6. the 500k trimpot just lets ya dial in for whatever ya wanna use as a transistor, guitar master.
    you could just replace it with a resistor, use a decade box and find the value that works best, and just solder it in.
    ;)
    good luck, and have fun!!

  7. you can tag it, good to be a low gain pickup booster. anyway thanks
