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 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.

Controls:
- LEVEL controls the output level
- TONE adjusts… read more the tonal balance
- GAIN sets the gain level
- CLIPPING toggle selects between asymmetrical clipping and no-diode mode (N)
- HIGH GAIN footswitch engages the high-gain stage
