The Warble Tron is an early handmade classic 60's style bulb driven Uni-vibe from JHS. This is likely to be one of the best Univibes you'll ever own.
It has flexible controls that give you a wide range of sounds, an oversized speed knob for easy onstage adjustments, and its flashing LED gives visual feedback of the speed.
This modern classic is in great shape and lightly used. It ships out the next day.
