LA Vintage Gear is proud to present this Dumble Overdrive Special #124, an exceptional example of the legendary work of Alexander Dumble. This amp comes to us from it's original owner who was referred to Alexander by Larry Carlton after hearing his Overdrive Special.

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.
