This is the ultimate noise making machine! It will turn your guitar into an almost unrecognizable blend of bleeps and bloops. But it does a lot more than that. You can blend in the amount of weirdness with the various knobs for an extra layer. Primary and Secondary knobs bring a first and second tone that be shifted above or below your original signal. With the Tracking control you can "delay" the pitch shifted signal so that you can get your initial attack and then let the magic happen. Speaking of magic, the Magic control is appropriately named, as this is how much chaos gets added to the sound. The Magic can be turned on and off via its own dedicated switch. Further real time controls can be added by connecting an expression pedal to the expression pedal jack on the Rainbow Machine. If you're looking for something a little different on your pedal board, perhaps the Rainbow Machine is what you're looking for!
