Keeley 1962X 2-Mode Limited British Overdrive has a wealth of great classic Bluesbreaker tones ready at a moments notice, so what could make it better? The 1962x is a limited version of 1962, built in batches, with an additional “KT88” high headroom mode utilizing MOSFET clipping. In the “KT66” mode you will get the same performance and gain range you get in the standard 1962, from mild light breakup all the way to full saturation. In the “KT88” mode, a MOSFET transistor is inserted in the clipping stage to produce a higher output, and a more forceful, focused and meatier sound. Layering gain sounds is one of the most tried and true ways of getting a deep rich tone. A tone that has a smoothness to it, has sustain to it. It let’s you sing! That’s exactly what Keeley done here in this hybrid of circuits. They´ve taken one of the most popular boosters out there, the Katana, and split it in half. Using both JFETs like valves in a British amp, we create pre-amp and output tube distortions characteristics.
