Critic Reviews

Under the microscope: Dumble Overdrive Special | MusicRadar

musicradar.com

The Dumble Overdrive Special Amp Head is lauded for its iconic status among guitarists, with its rarity and tonal excellence making it a sought-after gem. The amp's historical significance and association with legendary players like Robben Ford amplify its allure. However, the astronomical price—over £100,000—and limited availability make it an unattainable dream for most. The amp's powerful, muscular tone demands a certain playing style, which may not suit everyone. While clones exist, they fall short of the authentic Dumble experience. Overall, this amp is revered but remains an elusive piece of gear for the average musician.

In concert footage from Berlin 1983, Stevie Ray Vaughan can be seen using a Dumble Overdrive Special which according to corroborating sources was a loaner amp. This amp would make few if any appearances, as Stevie much preferred the Steel String Singer which he had previously borrowed from Jackson Browne.

"I used a Ram’s Head Big Muff for maximum distortion. I generally play clean or totally fuzzed out. The Dumble Overdrive Special amp introduced me to a wider spectrum of distortion and I pretty much stuck with the amp’s distortion and clean sounds."
