In the world of guitar amps, there exists one legendary designer and brand that very few ever get to meet, see, or play through. This is Alexander “Howard” Dumble and his namesake, Dumble amplifiers. Normally reserved to the paragon of players, you’ll find his amplifiers backing up such artists as Carlos Santana, Robben Ford, and even the late, great Stevie Ray Vaughan.
No two Dumbles are the same, but it’s the Dumble Overdrive Special that continues to reign as the man’s pinnacle design. The amplifier boasts unique sound and feel that is praised for its ability to enhance and uncover every nuance of a player’s technique and tone. And it’s this ability that has earned the amp a reputation for being one of the finest and most expensive ever made.
Yet, because these mythical amps are extremely hard to come by, we created the Synergy OS preamp module, our tribute to its iconic sound. The OS module packs the Dumble personality and user experience in a compact format, providing affordability and convenience that the original can never match.
