Evolving the Classic 808 Overdrive

When JAM Pedals first introduced the Tubedreamer in 2006, the mission was simple: build the world’s best 808-style overdrive. The Tubedreamer mk.2 pushes that legendary design even further. Delivering a warm, rich, and highly articulate overdrive, it features a carefully tuned midrange designed to effortlessly cut through any mix without ever sounding harsh or congested.

Whether you are looking for edge-of-breakup clarity or searing lead tones, the mk.2 features improved low-gain resolution. This provides finer control where it matters most, unlocking a massive range of highly usable tones at lower settings. At its core, the pedal proudly retains the legendary JRC4558D chip—the exact same component found in the most sought-after vintage units.

Next-Generation Features & Dynamic Control

The Tubedreamer mk.2 isn't just a reissue; it is a true performance tool built for modern players.

• Dynamic Clipping Options: A 3-diode asymmetrical clipping stage enhances touch sensitivity, naturally responding to your picking dynamics. New to the mk.2, you can toggle to a "No-Diode" clipping mode (N) for a massive, open, and amp-like response with maximum headroom.
• Dual Footswitch Design: For the first time, the high-gain stage is accessible via a dedicated footswitch, instantly transforming your rhythm tone into a soaring lead.
• Precision Internal Tweaking: Dual internal trimmers offer independent output level control for the high-gain stage in each clipping mode, allowing you to perfectly match or boost your signal.
• Smart Power-On: A selectable power-on state lets you choose whether the pedal automatically engages or remains bypassed upon startup.
