The Hughes & Kettner TriAmp is a 1990s all-tube head with three fully independent channels (Clean, Crunch, Lead), each with its own two-stage gain and treble/middle/bass controls, sharing presence and master. It uses nine ECC83s and a 100-watt push-pull power section built for EL34 or 6L6GC tubes, with relay switching and MIDI control. It gave players a rack-rig's worth of tones in a single head.
