I'd love to see a new version/conversion kit for the OD2. I have one and am happy with it, but I'd rather have a 2 channel overdrive than an overdrive with a boost. I'd like to be able to have a nice soft barely distorted sound for the slower songs and a good solid distortion for the rocking ones. I have a boss metal-zone that I use for solos, so I don't need a boost for that.
Anyways, that's what would fit MY style. I'm not sure how many ppl would feel the same
...also a multi-channel delay (with a tap) would be ideal too
