Hey folks. Anyone out there who uses/used this amp experience any lag when switching between presets? I've got a small lag and it is pretty annoying for switching between overdrive and clean within a song. I also use a Cusack PBT and get no lag from that, so I have to be conscious to treat the RH750 footswitch differently as to not have it sound sloppy. It's not to late for me to cart this thing back so any feedback is appreciated.
