Ok, so I used the Cubic a couple times Friday night at a gig. One time was for straight clean octave blended 50/50 with the clean to accompany keyboard and guitar solos. The next time was with a very fuzzy sounding octave paired with an envelope filter. It can definitely do the sub-octave fuzz nicely, and it sounds great through a filter. The last time was with the expression pedal doing long sweeps on lpf. The fact that it sounds so good with a filter makes me like the idea of a gate even more. At one point my guitar player leaned over to me and said it sounded bad-ass.
In this little video, I am basically just running through some of the settings I found be useful. At the end I turn on the Xerograph Deluxe to demonstrate how it sounds with a filter. I will do a video with the expression pedal and a direct comparison with a Boss OC-2 when I get the final version. Let me know what you think! Thanks!
