ROCK Bass: We have a ton of metal bass presets, but a dedicated rock bass pack is missing for us rock fans. Something in line with the couple of presets found in the Neil Dorfsman pack.
Pedals: Wahs, Whammys, tremolos, chorus, phasers, flangers, volume pedals, with controllable parameters using an expression pedal. This would make EZmix complete to me. I currently use amplitube solely for pre amp FX, but would be more than happy using only ezmix for all my Guitar and bass needs.
