The Rainbow Reverb is the ultimate digital reverb effect. The Rainbow is based on the well known and reliable DSP FV-1 platform and offers 5 reverb presets: Shimmer, Celestial,  Rotary Verb, Church and Spring. The Foxgear Rainbow, like all other Foxgear pedals, keeps the signal path 100% analog, with audio capacitors (no SMD) in the signal path and true bypass relay. It features five potentiometers to control various functions such as Tone, Level, Deep, Multi and Program.
