The Mooer E7 Polyphonic Guitar Synth pedal can transform your guitar into a typical electronic synthesizer without the need for special pickups or modifications to the instrument. The name is based on the seven different synthesizer presets, which can be edited independently of each other as desired. The presets include trumpet and organ-like sounds, sine and square LFOs, an 8-bit synth, and a synth pad. Each preset has its own Arpeggiator, High and Low Frequency Cut, as well as Attack and Speed, which allow guitarists to easily and intuitively shape the sound of the pedal - the E7 Polyphonic Guitar Synth offers endless possibilities!
