A classic Univibe® has a nice sloshy sound but it’s kinda big and to manually control the rate you need yet another big pedal. My solutions to this are my Neptune™ and Optune™ pedals which are less than half the size of the original Univibe®. Now I’ve taken them one step further and combined them in an even smaller package called the Nano Neptune™. The Nano Neptune™ stays true to that classic ‘vibe tone without sucking out your midrange. You can also manipulate one of the two sets of ‘Slosh’ (rate) controls by hovering your foot above its magic optical sensor.
