About The Pedal Creators
Everyone can build excellent boutique guitar pedals. Everything we do is to make that experience more accessible and user-friendlier. The Pedal Creators series are the best and easiest to build PCBs ever. Including most resistors and capacitors already soldered on board as SMD components, leaving the key values for you to experiment and craft your own tone. Now you can build a pedal you are proud of in less than an hour without any previous experience. What are you waiting for to become a Pedal Creator?
The Pedal creators – key features:
• Easy to build, no previous experience required. It’s like Lego for musicians.
• Fast assembly, finish a pedal in less than an hour. Play your favorite record and enjoy the ride along.
• 100% mistake-proof. Even my grandma can build one while she cooks.
• Build your own boutique pedal. Experiment with different values and make the pedal you always dreamed of.
• Easy to scale. Turn your passion into a money-making machine.
Project overview
Welcome to your new Optical Vibe Machine! With roots on the classic Uni-vibe, the guys from Akron, Ohio, did a serious job updating that classic pedal for the 21st-century demands with the same lush, pulsating, three-dimensional swirling sound you know and love and some modern accouterments for all you land-lubbers out there.
Designed to use with all kinds of instruments, pickups, and to play well with dirt, so nobody’s left waiting on shore!
Introduction
The guys at Earthquaker made some improvements to the original circuit. Smaller, more reliable by using LEDs instead of light bulbs. Able to run it at 9v-18v and adding some extra controls. So there was not much left for us to do but giving you an extra tonal option. Via toggle switch and bi Color led, you can get even more sounds out of it than the original provides. I highly recommend using sockets to experiment with the LEDs and solder the LDR’s in after getting an idea of how tall the led in the sockets will be. So you can match the height. While the original EQD unit uses a yellow LED, you could use a green/yellow led. With a minor difference in sound or a red/blue difference, there is way more present without a need to touch any knob, but it’s overall a bit sharper sounding. Personally, I used a single Color orange diffused led for a tone that made me more than happy. In case you‘re so in love with one specific LED, you can leave the toggle out and solder a jumper. I highly recommend experiment
