The Sidescroller is another videogame'ish fuzz with octave down, octave up and pulse width modulation.
Compared to the Arcadiator it has less controls (which often can be a good thing) and a unique pulse width modulation mode (however, similar sounds can be achieved with the Arcadiator if using the modboard). It also uses different methods to create the octave down/pwm that some people think sounds better.
