I did a search but near as I can tell the only octave up that's clean is the POG and I just sold mine because I hate the grainy sound and the latency, does not work on tracks at all. What I want is something that will give me a nice 8 string sound for fretless soloing. I'm not interested in the octave down, otherwise I'd just play above 12th fret all the time and be done. Has anyone run across a nice octave up that blends well? The Eventide harmonizers will do it but they are bulky and expensive. I've already got a green ringer box that does distorted octave up, not even close to what I need though cool for some things. Thanks for any tips!
