Joyo R13 XVI Polyphonic Octave Guitar Effect Pedal

The pedal features controls for mixing Sub Octave Control, Up Octave Control to adjust the pitch. Dry control increases the input dry volume. Modulation Control to unleash the organ tones.

The pedals Mod control is the thing you twiddle to get the big room filling organ tones, mixing the octave up and down to create some really fat sounding choir effect. Add a little tremolo, delay or reverb and you have a cool fake organ that will sound like a sweeping synth. Playing around with this pedal will take your guitar from its clean tone to another dimension, people will wonder where the synth is hidden.

The amount of functionality in this new pedal from JOYO is guaranteed to fatten up your tone, add some rich texture and introduce some polyphonic goodness.

The JOYO XVI polyphonic guitar effect pedal is part of the R Series of effects. The Revolution series pedals all feature metal housed stompbox. The R Series is the 4th generation and all feature some very cool ambient LED lighting.

Poly wants a cracking good FX ped.

I needed something on my pedal board to emulate bass guitar for constructing loops. Great bass sound but oh, so much more. Full control polyphonic octaver with modulation can create some wild sounds... In the same league as EH POG but better because of the mod control. Sturdy box and looks beautiful. Awesome value for the money.

I bought this to broaden the sound of my Bass and boy has this little unit delivered in spades. So flexible and really fills the room. As always, the service from Artist Guitars was second to none. The price was great and the whole delivery process was smooth as silk. I always check Artist Guitars first for my guitar needs and usually don’t have to look any further.

Polyphonic octave guitar effect peddle.

Excellent clean octaves but if single note runs are played to fast some odd overtones appear[the chip not fast enough to process the sound?],. This may or may not be a bad thing depending on your taste. Generally a useful device.
