Skreddy Pedals


Optical* Phase Shifter
With a Classic 1969 Voice

Chewy, lush, watery, vibe-style phaser with superior clarity and frequency response compared to a vintage specimen or a clone

Gorgeous and addictive tone, just swampy enough

The sweep has been optimized for the fullest possible range and intensity without going "over the top." Perfect balance between a smooth, symmetrical and a throbbing, asymmetrical waveform. This is not a bashful effect, but your guitar's tone will still shine through loud and clear.

Extremely low noise and low distortion, maintains neutral eq and volume footprint

Plenty of headroom. Fuzz friendly, before or after

Big knob for easy foot control

* "Optical?" Does that mean it has a real photocell? (BTW, it's not called a photocell, which is something that converts light to electricity, it's called a light-dependent resistor.) Yes; it has five of them! Four for the phase shifting and one for the speed controller. (Because an LED/LDR combination does a better job at smoothly sweeping through speeds than a reverse-log-taper pot does.)


(1) Speed

Goes from almost standing still to super fast rotary spin

LED Indicators:

Bypass (Green) indicates when circuit is active, off when in true-bypass

Speed (Red) indicates the speed of the sweep, always active

Signature vibe sounds
Thick, vocal modulation, sweet, other-worldly, moving phase shift, and rotating speaker emulation

Whether you set the speed to slow and subtle movement or throbbing, 3-D, shifting tones or rapid spinning, you'll groove as the Skreddy Swirl™ beautifies your guitar sound with its hypnotic and oldschool authority.

You can use this for any classic vibe effect, but you'll come up with lots of new uses for it; sure to inspire!

Is this a "real" vibe or a phaser?

Okay, a vibe is a phaser that's made with discreet transistors and optical electronics. The input stage of a vibe is similar to a simple discreet op-amp circuit, and each phase-shifting stage is made with a darlington pair with "bootstrap" positive feedback for high impedance (again, op-amp-like) which feeds both a negative and a variable phase-shifted positive signal to the next stage. At the end of four of these stages, the original dry signal is mixed together again at the output.

The Skreddy Swirl is made with op-amp gain stages in a very similar configuration and optical electronics, also in a very similar configuration (except I use LEDs instead of a light bulb, and I vary the degree of phase shift rather than the intensity of the phase-shifted signal in each of the four stages). The Swirl is dialed in to the same frequency response as a real vibe, and it sounds like a real vibe. I'd say the distinction between vibe and phaser is maybe a little arbitrary or perhaps a bit fuzzy, depending on how you look at it.
