The Garnet Rebel R90 is a 90-watt Canadian tube guitar head, a cornerstone of the Rebel family and the most widely produced professional Garnet amplifier. Its balanced, touch-responsive circuit makes it equally capable of articulate clean tones and aggressive crunch when driven hard, reflecting the broad stylistic demands of Canadian gigging musicians in the late 1960s. The R90 is the definitive Garnet amplifier and the most commonly encountered example in vintage collections.
