  • Hand-built in New Haven, CT

Started out as a vintage 70s OTA design, and it took a left turn. With experimentation and passing around the proverbial dish to taste, it morphed into a chewy and swirly beauty that can do all from subtle thickness, to wide open super vowel funk!

The Phaser MK1 is equipped with USA made Switchcraft jacks for reliable operation, and our tried and true click-less bypass system. This circuit allows for easy and silent effect switching, but also momentary operation for when you just need a little.

Handmade in New Haven, CT.

Common questions

My pedal isn't powering on — what should I check?

Make sure you're using a 9V DC center-negative power supply (standard for most effects). If the LED doesn't light, test another supply or cable.

Can I run it at higher voltage?

No — stick to a 9V DC center-negative supply.

The effect sounds weak or noisy.

Check cables and power first. On a daisy chain, try isolating the pedal on a clean, regulated output. Placement in your signal chain also shapes the tone — try moving it earlier or later.

What's the warranty?

Limited lifetime coverage for defects in materials and workmanship. If service is ever needed, most repairs turn around in 7–10 business days.

Under the hood

70s OTA roots, left turn taken

Started as a vintage OTA design and morphed into a chewy, swirly beauty.

Subtle to super vowel

Everything from gentle thickness to wide-open super vowel funk.

Two speed ranges

The Range switch re-gears the entire Speed sweep — syrupy, barely-moving lows or fast, vocal wobble, same knob throw.

From the bench

Every Dual Stage pedal gets built, tested and put through its paces on the same bench it was designed on — then backed by our limited lifetime warranty. If it ever quits on you, it comes home and we fix it.
