EarthQuaker Devices Arpanoid Arpegiator Pedal


The EarthQuaker Devices Arpanoid is a really interesting pedal that does something that you rarely see in electric guitar pedals. This is a powerful polyphonic arpegiator that takes your standard guitar signal and turns everything from a single note to complicated chords in to ascending or descending scales.

Quality Signal Chain

While the Arpegiator effect is expansive one of the really amazing things is the quality of signal they have going through. The dry signal is 100% analogue meaning that you get your tone at the end no matter what. The wet half of the signal is 100% digital but uses a very high quality set of converters so that you won't hear any difference to your sound.

8 Different Modes

The different modes on this pedal all relate to different scales and runs you can do with this pedal. From Major and Minor scales spanning 1 octave to completely random notes in a Minor or Major key you can get some really interesting runs that just require you to play a single chord or note.

Here's what EarthQuaker say about the Arpanoid Pedal

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.

Our pedals take 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!
Current draw is 52 mA.
