I don't know if it's possible with the current model but running two fx in parallel has been on my wish list in a pedal for a long time. Say take the h9 and run a delay and reverb in parallel. I'd even pony up for a more expensive model with 2x the power, say a h18, that could run two full fx in series or in parallel but have the series/parallel be a preset selection.
Another item I'd like to see is a studio style compressor. selectable between single and multiband with parallel blend options.
