Rivera Knucklehead Reverb 100W Guitar Head 1992

This amplifier features an all-tube design with a 100-watt EL34-powered output section, delivering classic Rivera versatility with massive headroom, articulate cleans, aggressive British-inspired crunch, and saturated early 90s high-gain lead tones. Designed by Paul Rivera and built in the USA, the Knucklehead Reverb blends American clarity with tight, focused low end and punchy midrange authority.

This example is in Very Good condition with cosmetic marks and discoloration to the tolex from normal use. The included footswitch functions properly but shows paint peeling and oxidation consistent with age. Fully operational and ready for stage or studio.
