JAM Pedals TubeDreamer Overdrive MKII

The overdrive all tubes dream of.

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 control where it matters

The mk.2 features improved low-gain resolution, providing finer control and unlocking a wider range of usable tones at lower gain settings.

Clipping options

At its core, the Tubedreamer retains the 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.

A no-diode clipping mode removes diode clipping, delivering a more open, dynamic, and amp-like response with increased headroom and clarity.

High-gain stage

A dedicated HIGH GAIN footswitch gives access to an additional gain stage, making the Tubedreamer mk.2 suitable for performance use.

Dual internal trimmers provide independent output level control for the high-gain stage in each clipping mode, allowing precise level matching or boosting.

Startup state

The Tubedreamer mk.2 allows you to define the startup state for both the effect and the high-gain stage.

By default, the pedal powers up with both disengaged, but any combination of on/off states can be selected.
