Description
The Hughes & Kettner TriAmp Mark III isn't just an amplifier; it's a tonal powerhouse designed for guitarists who crave the ultimate in flexibility and rich, authentic sound. This 150-watt all-tube amp head is a marvel of modern engineering, bringing together three independent preamp sections, each with its own distinct character ranging from sparkling '50s Californian cleans to thunderous modern high-gain tones. With six channels and 42 potential base sounds, the TriAmp Mark III is a master of versatility, allowing you to sculpt your sound with precision.
What sets the TriAmp Mark III apart is its groundbreaking Threedom Power Amp Technology, which features three pairs of freely assignable power tubes.

Whether you’re in the studio or on stage, the Red Box AE DI output and MIDI control ensure seamless integration into any setup. The included MIDI footboard and onboard noise gate add to the convenience, making this amp both a technical marvel and a joy to play.
