Larger V1 version. They def hit different. All analog photocell vibe. Excellent shape with velcro on bottom. I find that it is easier to tap tempo without remote due to its space between the buttons. V2 the buttons are very close and almost need the remote. The v1 does have the same red out for external expression/tap tempo. These were discontinued and sought after. Chorus and vibrato mode. Analog light bulb with a nice “proper” pulse. The unicorn of univibes.
