About this project
The PUSH.PULL pedal is a synth effect that turns your audio signal into a glitchy, crunchy, decimated, bitcrushed 8-bit erratic synthetic hyperdrive. It is intended to create sounds that sputter and oscillate in beautiful and odd and unpredictable ways.
The PUSH.PULL pedal is intended to be just as much a work of art as a pedal. A beautiful and intriguing, mysterious and other-worldly controller for friendly spaceships and/or evil robots. A science fiction portal. A pretty shiny electric thing with lots of knobs and joysticks that makes weird noises.
The PUSH.PULL is the start of something that I hope and wish to be a lifelong pursuit: making instruments. Yes, effects are instruments. Yes, I love them even more than traditional instruments, and I really love designing and creating them. More than anything, I love hearing other artists find something beautiful to play through them.
The PUSH.PULL Kickstarter Project will enable this artist to launch a series of pedals designed around the original pedal prototypes (as pictured above) containing lots of knobs and joysticks and delicious sputtering noise. The funding you provide will all go directly into the purchase of parts and manufacturing. The pedal will be hand wired and assembled by me, and I will build them with love and care. I want you to be happy.
As soon as the pedals are finished, they are to be offered to Kickstarter contributors first exclusively. As you will see in the incentive section, you may elect that the contribution you make will be "paid forward" towards a pedal purchase.
I am so impressed with what this site does for people, and so humbled by the opportunity to even present my ideas. As a musician, I am thrilled to find a stage to even play upon, let alone get someone to listen. Kickstarter is quite a stage to be presenting upon, so I'm a bit nervous. You begin my career in the art of sound design and electronics, or not. It is a once in a lifetime chance to bring this passion of mine to life, so I'm a bit giddy at the prospect. I believe and feel in my heart this is my artistic medium and for this piece I can't afford the brushes and canvas on my own. I am flattered and encouraged by your validation of this art through your contribution and complements.
The Madness Behind the Method
The audio that enters the pedal is amplified into a fuzz signal and then routed though the PLL, which tracks the audio and outputs synthetic tones. An oscillator is intertwined within the circuitry of the PLL to provide variations and oscillations. Voltage starves are utilized to make the pedal sputter and unlock the PLL. The signal is then divided into lower octaves and then sent into a low pass filter. All of these paths are controlled and mixed and modulated by the knobs and joysticks and light sensors.
A separate dry/wet mix knob is provided separately for the PLL, Octave Divider, and Filters respectively so that you may tune in a subtle trace of the signal as well.
As taken from Wikipedia:
A phase lock loop (PLL) is a control system that tries to generate an output signal whose phase is related to the phase of the input "reference" signal. It is an electronic circuit consisting of a variable frequency oscillator and a phase detector. This circuit compares the phase of the input signal with the phase of the signal derived from its output oscillator and adjusts the frequency of its oscillator to keep the phases matched. The signal from the phase detector is used to control the oscillator in a feedback loop.
Frequency is the derivative of phase. Keeping the input and output phase in lock step implies keeping the input and output frequencies in lock step. Consequently, a phase-locked loop can track an input frequency, or it can generate a frequency that is a multiple of the input frequency. The former property is used fordemodulation, and the latter property is used for indirect frequency synthesis.
In layman's terms, my pedal takes your audio, distorts it, synthesizes it, adds an octave layer, and then filters it.
In even more basic terms, my pedal makes noises unlike the previous noises.
PUlse Synth Harmonics . Phase (Un)Locked Loops
- The prototype I have finalized will be housed in a low profile 7" x 4.5" aluminum enclosure with a surface mounted faceplate made of recycled circuit board.
- 2 joysticks
- 4-8 knobs *
- 2-4 toggle switches *
- True-Bypass Footswitch OR toggle *
- Ocsillators intertwined in the PLL circuitry
- Selectable photoresistors for modulation of oscillators and filter by light
- Filter section added
- Voltage starve
- PLL voltage starve oscillator
- Octave divider
- Strong preamp
- Switches adding longer capacitator times and alternate routing of resistors
- Mixing section for oscillators
- Bright blue led pulses with PLL
- Self-oscillate capabilities
- 9V power supply
- Aluminum knobs
* if I add a true-bypass footswitch rather than a true-bypass toggle, I'll have to leave room for a foot! See below for what is still being considered in the design phase...
Still Under Consideration
You are part of this process! Contact me to let me in on your preferences before the project reaches a final PCB design: I'm listening, and perhaps I could make several variations if there is enough interest.
On the list:
- Footswitch (less knobs) VS Toggle (not Shoegazer friendly)
- Spectrum Ocsillation (a light that oscillates through the spectrum in different ways to control the oscillators/filters) VS cost & size of pedal
- Touch points on the exterior faceplate circuit board for true circuit bending with your fingers!
- Custom Labels/Finish?
[Your suggestions will be inserted here as the project evolves on Kickstarter]
Some Things You Might Want to Consider
- This pedal makes noise out of your signal. Sometimes it makes its own noises: like a pet! It will squiggle and splat, so if you're not into the unpredictable, it's not for you. You probably like bland food and plain donuts: s'ok, I can dig it. I like vanilla ice cream the best too.
- This is not a pedal that should be at the beginning of your signal. It does not amplify an acoustic instrument or microphone on it's own.
- It plays well with dirt pedals before the signal, and reverb/delays/filters after the signal.
- Just the look of it will create gasps from listeners and other musicians, and you will have to explain what it is again and again. And again. I like this part, by the way.
- Did I mention it makes noises?
I will keep you updated throughout the project. As soon as the funding is complete, I send out my orders for readily available parts and custom supplies (custom PCB's, custom joysticks, and recycled circuit boards) and the project starts to take shape. I will have projects completed and tested and shipped as soon as humanly possible. After all the parts are in, I estimate a 4-6 week turnaround for most of the orders, with pedals shipping as they are completed. Pretty fast for a boutique pedal!
"Let's start what we have come into the room to do"
What a wonderful thing, to be able to influence the art of sound: I hope you consider this too...
If pledges exceed the amount I am requesting to some joyous level, I will do my best to exceed the expectations of the PUSH.PULL pedal and add to its design in ways I could not consider in my goal to fund the project at a minimum. U Can Haz Moar! I really would love to integrate light modulation (the top tier) into the design, labels for knobs, and/or more controls. Perhaps two or three designs/models?
How do I know it could succeed with your help? As soon as I post pictures and videos of these pedals, I am inundated with emails and purchase requests. I have a market that is waiting to purchase my pedals right now. I need the enclosures, jacks, knobs, pots, joysticks, switches, and other ingredients. Ordering custom PCB's and joysticks overseas keeps this projected on the ground. I can reinvest immediately, and will do everything to make every penny you contribute work towards this thing I love to do. I can't do this alone. May karma lead the way. With a kickstart I will succeed.
Thank you for your consideration.
An earlier incarnation...
