All-tube circuitry for signature Krank gain.
The Rev Jr. amp head boasts an all tube dual channel head (two 5881s, three 12AX7s) with boost switch and a tube-driven active effects loop that gives even the most discerning tube amp enthusiasts an array of tones ranging from clean to high gain.
Krank Amplifiers have been a driving force in the popularization of lower wattage micro stacks with the introduction of the Rev Jr., the 20W version of the monster Rev Series 1 head and cabs and the first in the line of the Jr. Series of small amps.
