Positive Grid Vibrato pedal is available under the Mod effect group and is inspired by BBE Mind Bender. However Spark pedal does only offer the Vibrato effect while original BBE stompbox is dual and provides Chorus.
The Mind Bender is a dual mode analog vibrato and chorus pedal utilizing a BBD (Bucket Brigade Delay) circuit, patterned after 2 rare vintage pedals. Modeled after the Boss VB-2 Vibrato (pitch vibrato) and Way Huge Electronics Blue Hippo (analog chorus), the BBE Mind Bender produces a wide range of lush chorus, vibrato and rotating speaker effects. Features include a vibrato/chorus mode switch, speed and depth controls.
