Mooer E7: Polyphonic Guitar Synth Effects Pedal Review


Mooer E7 is a pocket guitar synth pedal. It is very versatile, and has several synth tones that you can use to practice or to gig.

In this article I review the features and capability of this little pedal that has so much to offer.

What is a Synth Pedal?

A synth pedal is designed to make the guitar sound as a synthesizer. As such, you can have an almost infinite combination of sounds generated by this type of pedal. Other pedals in this category are Source Audio C4 and Boss SY-1.

The first synthesizers were designed for keyboards. The heyday of this type of instruments was in the 80s, but since them we still have a lot of music that uses synthesizers in one way or another.

For guitar players, the synth pedal is a method to have the same capability. Another method is using a MIDI guitar, which you can learn about in another article.

The quality of synth pedals has improved considerably in the last few years. This happened because the circuits that were only available in a powerful keyboard can now be miniaturized into a tiny guitar pedal.
