JAM Pedals TubeDreamer mk.2

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.

CONTROLS:
* LEVEL controls the output level 

* TONE adjusts 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
