Jam Pedals TubeDreamer MK2 Overdrive Pedal
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.
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
