Picked this up a bit earlier this week . Have had some time to play with it and here are my thoughts. The octave tracks well even the B on my 5 string sounds decent but not perfect. And the octave mix works well overall a very good and useful Octave. The fuzz can go from mild to Crazy and when you mix in the sputter hang on it is going to be a wild ride. It also has a high gain switch and a high boost. The High gain is useful to me but the Bright switch is too much for me. without the brite switch on it works fine . I have not felt the need to cut the Highs but I keep the tweeter on my cab turned way down anyway. YMMV and just IMHO Anyone else have one of these that wants to share their opinions or settings? Or if you had one or used one and have something to say about it feel free.
