A to Z with roller for every single option is very uncomfortable/unhandy.
Example feature request:
cabs -> Marshall (1x12, 2x12, 4x12, mic SM57, 421, speaker V30, Creamback, etc.)
-> Mesa (same)
and so on
Same for the stomp:
OD -> Green, DS, etc.
MOD -> chorus, phaser, etc.
DLY ->
REV ->
and so on.
I know that software for PC/Mac is better, but this feature is helpful outside home/studio.
Thank you for the attention and sorry for my bad english.
