I love the Nano for it’s compact design, however the limited selection of presets with with the 2 footswitches let it down somewhat. I think the way you select between 2 presets per footswitch is a great idea but only being able to select 4 presets is extremely limiting and forces you to make this great compact device larger by having to add another footswitch to select more presets.
I would love to see the ability to select 4 presets per bank yes it would mean bending over to press the bank button by hand, but I think this would make the Nano an absolute power house of a compact pedal.
