About KOCH Twintone III

Let the Twintone III 50W Guitar Amplifier Head by Koch elevate your musical experience with its powerful and high-quality sound amplification. Retaining the best features of its predecessors, the Twintone I and II, this latest iteration has undergone a stylish restyle and boasts significant design improvements. Despite its compact size and manageable weight, the Twintone III packs a punch with its robust 50 watts of power, driven by two EL34 Power Tubes, capable of commanding any Koch extension speaker with ease.

The Twintone III is engineered for versatility, offering five speaker jacks to accommodate 4, 8, and 16 Ohm speaker cabinets, ensuring compatibility with a wide range of audio setups. The professional-grade 'Clean' channel remains untouched, continuing to deliver the warm and crystal-clear tones that have become synonymous with the Twintone series. The Overdrive channel, on the other hand, has been meticulously re-voiced to provide a more complex and richer gain structure, achieving a perfect balance between definition and depth. This allows guitarists to seamlessly transition from the pristine clean sounds to the exhilarating 'crunch' tones, and further into a saturated overdrive with infinite sustain.

The Twintone III is designed to cater to all types of guitar pickups, with the 'Bright Clean' guitar input specifically trimming the mids for humbucking pickups, ensuring the pure tone of the amplifier shines through. Additionally, the introduction of two separate, foot-switchable Master Volumes for Rhythm and Solo play on the front panel gives performers the flexibility to adjust their sound dynamically during live performances or recording sessions.

The Presence control has been thoughtfully relocated to the poweramp section, offering an authentic sparkle to both the Clean and Overdrive channels when adjusted. The long tank spring reverb, with its dedicated level control on the back panel, allows for precise tailoring of the effect, adding depth and dimension to your sound.

For recording artists, the Twintone III's output has been refined with an improved filter, providing true speaker-emulation to capture your favorite guitar tones authentically. Durable and built to last, the Twintone III 50W Guitar Amplifier Head stands as a testament to Koch's commitment to producing high-quality, professional musical equipment that meets the demands of both live performers and studio musicians.
