About KOCH Powertone III

Explore the sonic prowess of the Powertone III 50W Guitar Amplifier Head, a tour de force in the realm of heavy rock and metal amplification. As the latest iteration in the esteemed Powertone series, this amplifier head is engineered to retain the revered characteristics of its forebears while introducing a suite of enhancements that cater to the modern guitarist's demand for versatility and control.

The Powertone III stands out with its innovative Drive control on the Clean channel, allowing players to dial in the perfect blend of clarity and grit. The channel's expansive range extends from shimmering cleans with ample headroom to warm, lightly overdriven tones, ensuring that every nuance of your playing is captured with precision.

Channel 2, the 'Distortion' channel, has been meticulously re-voiced to embody a distinctive American-style character. This channel delivers high-gain and ultra-high-gain settings that produce a tighter, more complex, and harmonically rich distortion. The result is a sound that is both powerful and articulate, with exceptional depth and definition.

The Powertone III's OTS (Output Transformer Saturation) circuit is a groundbreaking addition. This mini tube amplifier within the amp can be overdriven to generate authentic power amp distortion at any volume, offering tube saturation that enriches both channels. The OTS Drive and Volume controls provide a harmonious blend of saturation and level adjustment, effectively functioning as an onboard effect that can be engaged or bypassed with the included footswitch.

Dual Master Volume controls are another key feature, allowing for seamless transitions between rhythm and lead volumes. This ensures your solos cut through the mix with commanding presence. The relocation of the Presence control to the power amp section, along with the new Depth control, further refines the amp's tonal spectrum, adding a lustrous sparkle and a profound low-end boost.

Connectivity is a breeze with the Powertone III's two FX loops, which can be configured in series or parallel and bypassed as needed. The amp's comprehensive MIDI control over all switchable functions, including channel selection, gain boost, and OTS circuit, provides unparalleled flexibility, especially when integrating the amp into a rack system.

For recording artists and live performers alike, the Powertone III features a Recording/PA direct output with speaker emulation, delivering studio-quality sound directly from the amp. This feature simulates the effect of a microphone placed in front of a speaker cabinet, providing a convenient and consistent audio feed for direct recording or PA system integration.

The Powertone III is designed to pair seamlessly with Koch speaker cabinets or any other extension cabinets, thanks to its versatile back panel equipped with five speaker output jacks for 4, 8, or 16 Ohm configurations.

Whether you're crafting your dream tone in the studio or unleashing it on stage, the Powertone III 50W Guitar Amplifier Head is a powerhouse of sonic potential, ready to elevate your music to new heights of expression and intensity.
