I need more time with the 2 Notes that I just received a week ago. But I have an issue... There are four modes on this preamp. A channel - mostly clean with a touch of tube breakup if gain is dimed. Bass and treble tone controls. B channel - more gain on tap, up to and including fuzz. Also, a sweepable mids control Hot Fusion - Uses B channel on top of A channel for mammoth distortion possibilities Cold Fusion - Blend mode between A and B, selected by a dial Okay, so I got a sound I like on A mode (which I would use for songs with cleaner tones). I would never want to use B mode alone, but I set it to some pretty high gain and then used the cold fusion mode to try to dial some aggression into the tamer A channel sound. The issue: I set the volume even between A channel and B channel, but when I blend, the signal seems to stack and is hotter than either solo channel unless the blend is exactly 50/50. Also, the blend control knob seems to work backwards: if I turn it towards the A channel side of the pedal, I get more of the B channel and vice versa. As I mentioned, I'm going to spend a little more time with it, but if I can't figure out a way to set this thing up for my needs, it will go back. A shame, since it has so much potential.
