I have been using a Shuttle 6.0 for a few months and all I can say is wow! My EBS rig is too big and heavy for me to load in and out of the car due to neck and back problems and now lives in the church 24/7, so this amp is an ideal mobile, light weight solution for me to travel to my students and gigs. I use mine through a Bergantino AE212 cab...sounds awesome!
