About KOCH Powertone III

Explore the world of high-quality sound with the Powertone III 100W Guitar Amplifier Head, a powerful and reliable successor to the renowned Powertone I and II amps. This versatile amplifier is a favorite among heavy rock and metal guitarists worldwide, known for its rich, warm, and organic tone.

The Powertone III preserves the best features of its predecessors while introducing several innovative enhancements to the original design. The Clean channel now boasts a Drive control, allowing for a wider range of tones, from sparkling cleans with ample headroom to moderately overdriven sounds. The Distortion channel has been re-voiced to offer a unique American-style character, delivering tighter, more complex, and harmonically rich high-gain and ultra-high-gain tones.

One of the standout features of the Powertone III is the OTS circuit, a mini tube amp that can be overdriven to create authentic power amp distortion at any volume level. This circuit adds a fantastic tube saturation to both channels and can be controlled with the OTS Drive and Volume controls. This feature can be considered an on-board effect unit that can be activated or bypassed with the footswitch.

The Powertone III also offers two separate switchable Master Volumes, allowing you to switch from Rhythm to Solo volume for more power during your solos. The Presence control has been relocated to the power amp section for a more authentic sparkle and operation on both the Clean and Gain channels. The new Depth control provides an incredible boost in the low end.

The back panel of the Powertone III features five speaker output jacks for connecting 4, 8, or 16 Ohm speaker cabinets, making it compatible with a Koch speaker cabinet or any other extension cabinet. It also offers two serial or parallel FX loops that can be bypassed, and remote MIDI control of all switchable functions for maximum flexibility.

Whether you're performing live or recording in a studio, the Powertone III 100W Guitar Amplifier Head is equipped with a Recording/PA direct output for a speaker-emulated sound, ensuring the highest quality audio output. Experience the power and versatility of the Powertone III and create the sound you've always dreamed of.
