The KR12 Head and Cabinet is EL34-based. The Cabinet features an open back design which provides a unique presence and sound consistent with the KR12 Combo. It is the result of Louis Rosano’s longstanding work with Hubert Sumlin and Keith Richards. The KR12’s four inputs offer different levels of gain from crisp, crunchy throatiness to a hefty vintage rock bark.
Based on the Louis Electric M12 used by Sumlin, the KR12 Head & Cabinet has several gain options and unmatched headroom, but preserves the warmth of a 1950’s and 1960’s vintage style amp. The KR12 Head & Cabinet has Volume and Master Volume controls, middle, treble, bass plus Presence. And, lurking on the underside of the chassis, a little Damping knob which adjusts the level of negative feedback which is an excellent feature to have because most amplifiers only offer fixed resistor which limits tone shaping.
