Guitarist Bobby DeVito demos the new Mad Professor Old School amp and some pedals at Summer NAMM 2009. I love the new amp! It delivers great tone and crunch without weighing a ton. Bobby also demos some pedals including one of my favorite MP pedals the Sky Blue Overdrive. It is by far one my my favorite overdrives due to it's rich harmonic content and singing sustain! Check them out if you ever get a chance!
