EarthQuaker Devices Arpanoid V2 Polyphonic Pitch Arpeggiator Pedal

Need to climb out of a creative rut? The Arpanoid Polyphonic guitar arpeggiator is like nothing you've ever heard and is a bonafide mind-blower. This pedal would have been impressive even if it was monophonic but the fact that you can arpeggiate single notes, double stops and complex chords is pretty mind blowing in practice. They give you 8 total arpeggio modes: 4 major and 4 minor, including a random mode for either tonality. It takes a little bit of experimenting to settle in, but the controls are simple and effective so it's a joyous journey. You can fine-tune your selected arpeggio by setting it's speed with the rate knob, choosing whether your arpeggio goes upward, downward, or both, and even how many steps of the arpeggio are played out. The step tool is really fun because it opens up a world of rhythmic patterns and melodic stuttering that can make your guitar sound like a synth gone wild. With the Arpanoid, EarthQuaker Devices proves its leadership in creating circuits that keep guitar playing fresh and exciting no matter what genre or style you prefer. That being said, these circuits are optimized for anything with a 1/4" plug, so if you're behind a keyboard or thumping on a bass, this one's for you too.

Hi buddies, welcome to the first dedicated compact polyphonic pitch arpeggiator effect pedal for electrical guitar! What does the Arpanoid do? The Arpanoid™ takes whatever you play and transforms it into an adjustable ascending or descending scale. It features 8 intuitive and expandable modes and will work on complex chords as well as single notes in any key. The Arpanoid has an all analog dry signal, all digital wet signal and true bypass switching. Like all EarthQuaker Devices pedals, this dude is handmade one at a time in sunny Akron Ohio.

1. Rate: Adjusts the speed of the sequence.

2. Up/Up-Down/Down Toggle: Switch to control the direction of the sequence. All the way left is up, the sequence will continually repeat going up. In the middle is up/down, the sequence will continually repeat going up then back down. All the way right is down, the signal will continually repeat going down.

3. Step: Selects how many notes there are in the sequence.

Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

  • For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

  • For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.


This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
