With 20 Watts of power provided by a pair of EL84 tubes, the Hughes & Kettner Edition Blue 20th Anniversary is designed to go from clean to crunch to rock. The 12" Rockdriver Cream speaker was created in a joint effort with Eminence, and is described as a mid-Atlantic blend combining the best of American and British tonal properties. An onboard spring reverb and an effects loop round out the Anniversary model's feature set.
