When JAM introduced the Tubedreamer in 2006, their goal was to build the best 808-style overdrive. That’s what they built then, and what they’ve pushed further with the mk.2. The Tubedreamer mk.2 delivers a warm, rich and articulate overdrive, with a carefully tuned midrange that cuts through a mix without ever sounding congested or harsh. Improved low-gain resolution provides finer control where it matters most, unlocking a wider range of usable tones at lower settings. At its core, the Tubedreamer retains the legendary JRC4558D chip, just like the most sought-after vintage units. A 3-diode asymmetrical clipping stage enhances touch sensitivity, responding naturally to picking dynamics and fretting nuances. New to the mk.2, a no-diode clipping mode removes diode clipping, delivering a more open, dynamic and amp-like response with increased headroom and clarity. For the first time, the high-gain stage is accessible via a dedicated footswitch, turning the Tubedreamer into a true performance tool. Dual internal trimmers provide independent output level control for the high-gain stage in each clipping mode, enabling precise matching or boosting. A selectable power-on state lets you choose whether the pedal engages or remains bypassed on startup.
