SWEET SOUND Ultra Vibe 16/18 - Swirl

If you want simply the best vintage Uni-Vibe sounding pedal available, then look no further than the Ultra Vibe II. The Ultra has the modern advantages of true bypass 1/4 W carbon comp resistors custom-made photocells and the right bulb, a smaller footprint (4 3/4" X 6 5/8") for more room on your boards. Soundwise, the Ultra-Vibe has few peers. It's warm and breathy with a lush 3-D liquid quality that envelopes your signal effortlessly.

Just about any passive type volume pedal or expression pedal will work with the Ultra Vibe. Of course some better than others, due to the value of the pot in the pedal. The ideal value would be a 100K reverse log taper. But I have found that many other values will work satisfactorily. To conserve space the UltraVibe uses a ¼" stereo tip, ring, sleeve switching jack for the controller input. You can use it as is with expression pedals where the cord is already connected to the pedal such as Roland, Ensoniq and other keyboard expression pedals. To use a passive volume pedal you will need a special cord that consists of a ¼" stereo plug on one end and splits into two mono ¼" plugs. These are the same cables used in the channel inserts on mixing consoles and are readily available at most music stores.
