Roland US-2 Guitar Synth Selector

Roland US-2 Vintage Guitar Synth Selector


Use One Vintage Roland Guitar Synthesizer Controller to Play TWO Guitar Synthesizers


The incredibly rare and highly sought-after Roland US-2. Play any two Roland vintage synths with one controller.



About the US-2:




For those of you unfamiliar with the US-2, you plug a vintage Roland guitar synth controller, like a G-202, G-303, G-808, G-808, or a bass unit like the G-88 or G-77 into the female 24-pin input connector. Plug the channel A and B outputs into a vintage synth, and you now ca play either synth A, synth B, or both. The US-2 receives its power from synth A. However, you can plug a bus converter, like a BX-13 into the synth B output, enabling you to play a 24-pin and 13-pin synth at the same time.

If you are familiar with how the GR-300, GR-33B or GR-100 look when they are working, well, you get the same light show! The front panel LEDs flash just like they do on the synths, until you push down on the footswitch and engage an output. Then the respective LED lights solid.
