Out of the box, the Lunar Phaser provides tremendous tonal range, but under the hood this pedal is a powerhouse of control and flexibility. Every stompbox in the One Series line is compatible with the Neuro Mobile App (a free download for iOS and Android). The App offers an extensive list of additional phaser, flanger, and chorus algorithms - each can be downloaded directly to your Lunar Phaser. The Neuro App also features an extended set of adjustable parameters including the Frequency (the center point of the modulation), Output Level, embeddable Tremolo, Low Retain, a Parametric EQ, Advanced Signal Routing and more. Plus, every One Series pedal is fully MIDI compatible when coupled with the Neuro Hub (formerly Soundblox Hub), giving you the power to save up to 128 presets. This pedal is in good condition.
