CONGRATULATIONS

On your purchase of the T-Rex 8-ball pedal!

Delivering 2 channels of polyphonic octave generation, you can foot­switch between two separate blends of dry signal, low octave and high
octave.

For instance, you may want to add a little high octave “shimmer” to
lead lines and use plenty of low octave for powerful riffing. Or maybe
your music demands two levels of octave generation – a little and a lot.
The 8-ball allows you to set up each channel for the exact amount of
octave signal(s) and you can then easily go from one to the other.

The 8-ball uses a polyphonic, fast tracking DSP engine to generate the
octave signals but your dry, unaffected signal remains analog and is
buffered when the pedal is bypassed.
