JAM Pedals Tubedreamer mk.2

When we introduced the Tubedreamer in 2006, our goal was to build the best 808-style overdrive. That’s what we built then, and what we’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.
