Long regarded as one of the best 808-inspired overdrives available, JAM Pedals has raised the bar with the release of the new Tubedreamer Mk2. While there are countless 808-style pedals on the market, the Tubedreamer has consistently stood out because it offers a less mid-forward, more linear tonal character. This unique design allows the pedal to reveal greater detail and nuance in response to a player’s dynamics, delivering a more expressive and transparent overdrive experience.

The Tubedreamer Mk2 introduces several new features that enhance its versatility and performance. First, there is a “no clipping” mode, which bypasses the diodes to deliver a higher headroom, less compressed sound from the JRC4558D op amp. This mode is ideal for pushing other pedals or your amplifier without adding layering on additinoal clipping.

Additionally, the High Gain toggle switch has been upgraded to a footswitch, transforming the Tubedreamer into a true two-function pedal. Users can set the high gain level for both the clipping and no-clipping modes by adjusting internal trim pots. This functionality is particularly useful because the volume increase in the no-clipping mode is naturally greater than in the diode mode. Conversely, players can tweak the gain in the clipping mode to match the loudness of the non-clipped mode. JAM is alwasy one step ahead and knows that performers will want to tweak the Tubedreamer exactly to their needs. 

In the crowded world of effects pedals, it is well known that nearly every manufacturer produces a Tubescreamer variant. However, not all have mastered it, and that mastery is precisely what makes the Tubedreamer Mk2 exceptional both sonically and in its tactile response. If you think you like Tubescreamers and especially if you think you don't like Tubescreamers, you you owe it to yourself to try the Tubedreamer Mk2 and experience its unique approach to the classic overdrive sound.

In the words of JAM pedals....

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.
