the end of your audio is saturated in tails of sputtering electricity sounds.

a crunchy analogue sounding bit-crushing synthy thing

a sputtering fm-tuning finish to notes

a fuzzy pitch shifter

a pulse width tremolo synth can be applied to the incoming audio

a similar sound to a blaster as wielded by Han Solo can be achieved pew-pew

a self-oscillating madhouse of recharging capacitors

an additive of not-usual effectology

 a distorted, glitchy, fuzzy bass synth

a drone full of clicks and pulses

an 8 bit erratic synthetic hyperdrive

when a combination of knobs are turned up into inaudibly high frequencies, it self-oscillates in unusual ways, often only when an audible signal is not present. This unique self-oscillation can cause frequencies to pulse in the absences, creating synthetic pulses when applied to rhythms.

when a combination of knobs are turned down to droning audible frequencies, it acts like an Atari Punk Console with frequencies only modified by the incoming signal.

The push.pull pedal is a synth effect based upon the PLL (Phase Locked Loop) IC, in which the PLL has been “unlocked” and let loose through 10 knobs.

  • 10 knobs
  • makes your audio really, really loud
  • true bypass/power priming switch
  • voltage starve
  • yellow led
  • self-oscillation
  • surface constructed from recycled circuit board
  • thick epoxy makes it stompable
  • 12v

i had attempted to make the push.pull and push.pull spectrum for sale to the public. i had picked a very large (an expensive) pedal to manufacture with lots of parts that were difficult to find. i sought funding through kickstarter and lost. i had promised to make these pedals to a few people regardless of funds, but the list of “things that keep me from doing things” for manufacturing these particular pedals would make the process a risky maneuver, and i want users to be happy.

the sputterbox is very close to emerging as my first true entry into the shoegazer market. it sounds so much better than my first two. basically, i kept to the philosophy (in tweaking the previous design) to make sure it had the widest variance i could achieve in the pll circuit for each knob without compromising the original sputter that i fell in love with in the first place. since joysticks pretty much are only available in 100k, the long and painful decision to remove the idea of joysticks finally came to be. trust me, the artist inside me resisted this for about a year. i seriously would spend nights concocting notions of paying for custom joysticks though my non-money, and still be able to fit sixteen aluminum knobs into the budget. wondering where to get the recycled circuit board was also a favorite topic of avoidance.

i have three more hurdles:

  1. the PCB: i am still working off stock PCB’s from RS that resemble my breadboard. i still am not able to make my own or design one in EagleCAD (yet) that i can confidently say will arrive not looking like a noob had designed it. although having an official rock-solid PCB is not a concern to some, most would like the innards of the pedal to resemble professional wiring and solid pretty green and copper circuit design. i need a pal.
  2. the assembly line/packaging.
  3. the funds to do 1 and 2.
a couple things to check out this week:
  • what does a guitar or bass sound like through this? i wouldn’t know.
  • does the pedal play well with others? i have a lot of friends it can play with!

and a couple hopes:

  • that a partner-in-crime emerges: someone who digs the idea of making these pedals but really knows the details of  circuitry and PCB’s.
  • that someone who want to hire me to design the look of their pedals: electro-harmonix, i’m looking at you.

not ready yet to be multiplied, but is an actual thing that can be built for people.

and that’s where i’m at today.

videos later this week.

    I look forward to the videos, as the description makes me want one. How much would you be selling them for?

      I was setting out to make the videos today, but I’m swamped with work, so it’ll have to happen this week sometime.
      As far as price, it really will depend on how many I can crank out and how much the parts are going to cost me altogether (the big mystery being the cost of the custom circuit board itself.) Electronics, knobs, pots, jacks, enclosure, switches, glaze & circuit board cover + labor = I don’t know 🙂 Sorry! I’ll keep you posted, and thank you for the interest.

      • Edward says:

        I don’t mean to undermine your hardwork, but would you be willing to share a schematic of the circuit board? Or possibly a DIY kit? How much did the original cost to build?
        I look forward to the videos to come.

      • coloringpad says:

        I have not contemplated a diy kit as this was just born: the original cost about 100 us total (knobs, switches, jacks, enclosure & circuit board cover cost about 70 alone), but i put about 100 hours into this over the year, and that never seems to get factored in to the cost! The schematic will be retained until I actually make 1 dime from this excursion: sorry!

    Where are you located since you said USD? I’m really interested in a PLL effect for a multitude of uses. Do you have any useful links for PLL basics? I’m really interested in building one. As for not making a DIY or offering schematics, I didn’t expect you to! Thanks for the response; please put some videos up!!
