I would like to see built in compressor fx if possible (I assume that will never happen on current hardware other than the few boxes that have it built in already) or a revamped reverb (I also assume that will not happen, but it would at least ne nice to have a steeper high cut filter than max 2.0K as it is now..(I also assume that won't happen)

So my main suggestion is

Equalizer's with more Q points (there are only 3 currently, so if you use hi-pass and low-pass you only have one narrow band eq to work with) and ability to go wider than 0.7
