Hi Walter,
I think it adds a lot in an acoustic setting. A little bit of amplified foot tapping can make quite the difference, I was surprised too! 😉
When you play with a drummer or percussionist it’s redundant but I’ve seen a stomp box being used quite effectively for a lot of solo artists and duos that only use guitars.
I bought it online here in the UK a few years ago. The Wazinator I’ve got is quite large so if you want to travel light it’s probably not the best choice of stompbox, and it takes some heavy equalisation to make it sound decent 🙂
Let me know your experience if you end up getting one!
