How can I use the Sub 'N' Up Octaver to create a shimmer effect?
In order to do this you will want a reverb pedal connected after the Sub 'N' Up. Select the Poly Mode on the Sub 'N' Up, Turn the Up octave all the way up and the Sub octaves all the way down and dial in the dry to taste. Then on your reverb pedal, set it so it is 100% wet. This is the basic direction to get this type of sound. Form here you can simply experiment adding modulation, playing with different reverb types and adding other octaves. When it comes to creating great sounds, experimentation is the key. Often the best thing to do is ignore what the controls are labeled as and simply twist away.
You can substitute a delay pedal for a reverb by selecting a short delay time and adding a fair amount of feedback to taste.
