About this model
The Donner Harmonic Square is a compact modulation pedal designed for guitarists and bassists looking to add movement and texture to their signal chain. Modulation pedals in this category typically offer effects such as chorus, flanger, phaser, or vibrato, allowing players to shape their tone with rhythmic or pitch-based colour. Donner's pedal range is generally aimed at players who want straightforward, pedalboard-friendly designs without a complex signal chain - the Harmonic Square fits that brief as a grab-and-go modulation option suitable for rehearsal, gigging, or home recording.
A great opportunity to own a Donner Harmonic Square at this price point.
