Imperial MK II

First introduced in 1993, the Imperial has become a proven favorite of guitarists seeking authentic vintage tone. Utilizing all-tube circuitry, traditional spring reverb, and a specially voiced, highly resonant cabinet, the Imperial captures the true experience of playing a well-worn vintage amplifier – both in tone and feel.

Twenty years of research and development have been engineered into the new Imperial MK II to capture the best of authentic vintage tone while offering a number of useful new features.
