The Sumo 1000 was ordered to create a flexible and lightweight rig paired to a Mesa preamp pedal. After a gig and two rehearsals with it I am really happy at how powerful the Sumo is and how closely my light rig matches my Mesa Venture 600 Mosfet amp. Didier you have created a truly great piece of kit at an astonishingly musician friendly price point. Kudos to you sir!
