Redefining the phaser effect from the ground up, Empress Effects has created a phaser pedal unlike anything else on the market. Employing a unique VCA based design, the Empress Phaser Pedal offers unparalleled signal-to-noise ratio. Choose between 2 stage, 4 stage or an Empress exclusive 3 stage mode; all controllable via tap tempo sweeping through an impressive set of 8 waveforms.

The Empress Phaser Pedal is the next generation in the evolution of digitally-controlled analog technology. It features an all-analog signal path but is controlled by a microprocessor, allowing it to maintain all its character and analog flavor while adding a ton of possibilities for control and adaptability. Sure, it does the classic jet sounds, super funky auto-wah and ring modulators, as well as having vibrato and Univibe sounds on tap. But what really sets the Empress Phaser Pedal apart are the auto modes: envelope following, audio-triggered sweeps, rhythms and direct control are just a few of the settings found on the Empress Phaser Pedal.

It also offers unsurpassed connectivity by featuring expression pedal control as well as accepting control voltage, external tap, external audio control and MIDI. All of this comes in a rock solid die cast aluminum enclosure with true bypass keeping things clean.

Features & Specifications

The Empress Phaser Pedal gives you maximum control in a small package. In addition to tap tempo and super musical auto modes, you can now control your phaser via control voltage, expression pedal, external audio input and MIDI.

  • Killer Sound Quality - The Signal to Noise ratio is around 104 dB.
  • 8 Auto modes - Envelope follower, center & speed, speed(sine), speed(square), audio sweep trigger, random level trigger, rhythms and direct control
  • Tap Tempo with Ratios - Use tap tempo to set the phasers speed; the ratio selection makes fast tempos and triplet based phase times easy.
  • 2 / 3 / 4 Stages - Select 2, 4 or, an empress exclusive, 3 stages
  • 5 Rhythms - Rhythms let your phaser boldly go where no phaser has gone before
  • Ultimate Control - Control over width, speed, resonance, waveform, and number of stages.
  • 8 Waveforms - Phase through sine, triangle, asymmetric sine, swung sine, sawtooth, reverse sawtooh, square and step waveforms.
  • True Bypass - The Empress Phaser Pedal employs true bypass, so you can be sure that it's not affecting the signal when disengaged.
  • Gain - Set the output gain of the phaser to match your bypassed signal or use up to 6dB of boost to really drive your preamp
  • Small Size - The enclosure measures approximately 4.5" by 3.5" by 1.5", which is delightfully small when considering all the features packed into this unit.
  • Unsurpassed Connectivity - The Universal Control Port allows you to connect an expression pedal, external tap switch, control voltage, external audio input and MIDI all using a standard 1/4" jack!
  • True Display LEDs - Extremely responsive LEDs always let you know what the phaser is doing and help you adjust the sensitivity in the auto modes.
  • 45 Day Money Back Guarantee - If for any reason the Phaser isn't for you, send it back within 45 days for a refund. Read our Guarantee for more details.
  • Four Year Warranty - The Empress Phaser Pedal comes with a two-year warranty. Read our Warranty for details. You can extend the warranty to 4 years by simply registering online.
  • Great Value - The Empress Phaser Pedal is the last phaser you'll ever have to buy. It does everything a phaser can do and more!
  • The Empress Phaser Pedal runs on standard 9V negative tip DC power, but can safely accept up to 18V. It draws about 120mA.

Manual & FAQ

Empress Phaser Pedal User Manual

Question: What kind of bypassing does the Phaser have?

Answer: The Phaser has true bypass switching. It uses a relay to switch.

Question: What kind expression pedal/volume pedal should I use for the blend exp input?

Answer: The pinout of the expression pedal should be TIP=output, RING=input, SLEEVE=ground. There's a list of expression pedals on this page that work with the control port. They should also work with the blend exp input. Volume pedals probably have too high of a pot resistance to work with the blend exp port, but you can give it a shot!

Question: What expression pedals can I use with this pedal?

Answer: The pinout for the expression pedal is TIP=signal, RING=3.3V power, SLEEVE=ground. So your expression pedal has to have that pinout. Here's a list of pedals that we know work. Please let us know if you find any other pedals that work!

Mission EP-1 and EP-2 (no polarity switch, polarity switch, respectively)

M Audio EX-P (has polarity switch)

Roland EV-5

Lead Foot LFX-1

Boss FV-500L

Moog EP-2 (we've tested the EP-2, and it works. it has been replaced by the EP-3 which we haven't tested yet)

Question: I play bass! Can I rock out through this pedal?

Answer: Yes! All of our pedals play nicely with bass. Check out the "Features & Specs" section for information on the frequency response of our pedals. We have lots of customers who play bass through our pedals!

Question: The pots turn easily, so they move when I accidently hit them during a show. What can I do?

Answer: One of our customers has a great solution to this problem. If you wrap rubber bands at the base of the pot it makes it harder to turn.
