Send the crowd good vibes! The T-Rex Engineering Beta Vibe is a chorus effect pedal designed for use with electric guitar but is capable of being used with any electronic instrument that you would want to use chorus with. Yes, this is a new pedal.. never sold! The pedal has a 1/4 inch input and output and also has MIDI capabilities. The configuration of the T-Rex Engineering Beta Vibe is quite easy to follow. The pedal has knobs for mix, depth, volume, and speed, and also has two buttons - one for mode and one for MIDI. It has two separate buttons - one for engaging the effect and one for choosing between a slow and a fast effect and for tapping out the tempo. • MFSKU Beta Vibe
