1. I would like an octave generator effect, much like the Electro-Harmonix POG. The best feature of this pedal is that chords sound like an organ. I have not found anything that can emulate this on the Eclipse as of yet, unless you have a suggestion.
2. Maybe a tube preamp / tube compressor model. I think a lot of people are liking the Fractal Audio Axe-Fx more than the Eclipse because it's algorithms sound warmer, and more organic, and it's more guitar-player-friendly.
3. This isn't necessarily a preset suggestion, but it would be great if tap tempo could be set up more easily, and accurately in that regard. This is another area where Fractal Audio excels – making the unit more live-performance friendly. As it stands, the Eclipse is really more suited for studio use.
