Hughes & Kettner TriAmp Mark 3 150W 6-Channel Tube Amp Head (Demo Unit)
Changing the Game. Seriously.
TriAmp Mark 3
No limits. No compromises. This is what you get when 30 years of tube amp expertise combine with an absolute freedom of engineering. The result is an amp boasting a range of professional sounds not offered by any other amp anywhere on the planet. And best of all, TriAmp Mark 3’s breathtaking versatility and inspirational tonality is matched only by its ease and joy of use.
Highlights
Each of TriAmp Mark 3’s six independent, action-packed channels represents a whole era of tone, and each of these six eras can be routed to three independent tube power amps.
Think the Unthinkable
You can also combine two or even all three of the power amps, merge different power amp characters, and play TriAmp Mark 3 with up to 150 watts of sheer tube power. This effectively lets you custom tailor your amp in the amp, recalling up to 128 sound constellations with the touch of a button via MIDI.
Threedome Power Amp Technology
And if that’s not enough, TriAmp Mark 3 leaves the factory in St. Wendel, Germany equipped with two pairs of 6L6 power tubes and one pair of EL34s — but it works equally well with other tube types too. The revised TSC System (Tube Safety Control), which automatically and constantly biases tubes and keeps your amp in good health — allows you to combine KT66s, KT77s, KT88s, 6550s, 5881s, 7581s and/or 6CA7s. Imagine what this could do for your trademark sounds. TriAmp Mark 3 genuinely lets you usher in a new era of tone!
42 Amps in One
Get all the true tube tones you want and all the stage-rumbling wattage you need! The Hughes & Kettner TriAmp MKIII head comes equipped with a trio of independent power amp sections that can be used independently or combined. The best part? You can use a wide range of different tube types to conjure authentic American and British amp tones (and create your own custom sounds, too). Each of the TriAmp MKIII’s three preamp sections has a pair of channels, and you can route them independently to the power sections. The result? You’re plugged into 42 different amp possibilities – all from one amp head. You also get a DI output with Ambience Emulation, full MIDI control, intuitive controls, an onboard noise gate, and much more.
