The Hughes & Kettner Tube 100 is a straightforward all-tube 100-watt head aimed at players wanting classic valve tone without the complexity of multi-channel switching. Its two-channel layout covers clean headroom and driven tones, powered by a quartet of EL34s with a well-voiced passive EQ. The Tube 100 represents H&K's simpler, more traditionalist side.
