I've been using a Boss GT-100 for the last few years.
I still have not received my helix, still waiting for it, but reading the manual...
One option I am missing is the possibility to increase/decrease the volume using a footswitch.
I know it is possible to have a volume block, or use snapshots...
But what I mean is to be able to increase the volume (1dB for example) each time I stomp on FSx, and decrease the volume (1dB) each time I stomp on FSy.
So, in case you are using the wah and you want to adjust the volume on the go, you can touch a couple of times the footswitch, and decrease it to the point you want...
Or maybe the programed boost is not loud enough, so you stomp three times the increase switch up to the level where the barman runs...
