I spend the majority of my time behind a keyboard rig, but I've recently been playing more guitar and bass in one of my current bands. For ease of setup - not to mention relief for my aging back - I've been using an Alairex HALO, a Two Notes Audio Torpedo CAB and an Eventide H9 Max. I just plug into my keyboard sound system, and it actually sounds pretty great; plus, I can configure the rig to bass duty instantly for the few songs I play one of those.
I can't help but feel a bit odd showing up with only three pedals, though...probably similar to the discomfort some drummers I know tell me they feel when it comes to gigging with electrionic drums.
How widely are players adopting the ampless approach?
