Was thinking about waiting for the G5, but I think its going to be overkill for what I need it for. Plenty of features on G3. Anyway I had a couple questions. Does looper work interdependently? Another words does it have to be in one of the 3 banks? Also how good is tuner and the phaser? I got two pedals I'm looking at flipping (Korg pitch black, MXR Phaser)..
