Dumble Overdrive Special #124 – The Holy Grail!

LA Vintage Gear is proud to present this Dumble Overdrive Special #124, an exceptional example of the legendary work of Alexander Dumble.

Built during the late 1970’s to early 1980’s, #124 delivers the harmonic complexity, dynamic response, and touch sensitivity that define the Dumble sound. This is a serious player’s amplifier with the versatility and authority to excel in both studio and live settings.

Rated at 100 watts with a 50/100-watt switch, the amp offers massive clean headroom in full-power mode, tight low end, articulate mids, and clear, singing highs that hold together at volume. Switching to 50 watts introduces earlier breakup and a softer, more responsive feel, ideal for expressive lead work and controlled studio environments.

Equipped with 6L6 power tubes, #124 delivers a bold, American-voiced tonal foundation with strong low-end presence, open top end, and a focused midrange that sits perfectly in a mix. The clean channel is full and dimensional, while the overdrive channel produces the unmistakable Dumble voice: smooth, sustaining, and harmonically rich with outstanding note separation.

The 3 toggle switches expands the amp’s tonal range, offering multiple voicings within a single platform. From glassy cleans to thicker, mid-forward drive tones, these controls allow precise shaping of feel and response without sacrificing clarity.

As expected from a great Dumble, the touch response is immediate and expressive. The amp tracks picking dynamics and guitar volume changes effortlessly, moving from clean to overdrive with no pedals required. Notes have a three-dimensional bloom, with clarity at the front and a rich, musical sustain.

Rare, highly collectible, and sonically inspiring, Overdrive Special #124 stands as one of the finest examples of Dumble’s work and remains among the most sought-after amplifiers ever built.
