Is anything random in life or do all things happen for a reason? Vibrato (for better or worse) has always been restricted to a speed knob. This inherent problem with this design is that it inevitably leads the musician and the listener wanting change. If you’re an “always on” effects person, I know that you want to spend more time enjoying your effect and less time turning knobs. Genius in its simplicity, Mid-Fi’s “Random Vibrato” will leave you in anticipation of every unique passage as it helps you bring new life to the same guitar.
