Critic Reviews

I played the last Overdrive Special that Dumble worked on | Guitar World

guitarworld.com

Playing the Dumble Overdrive Special is an enlightening yet humbling experience. Known for its unforgiving nature, this amp reveals every flaw in your playing while demanding top-tier performance to shine. The overdrive is powerful and awe-inspiring, yet the clean tones can be challenging to control. While the Dumble sound remains magical, the absence of Howard Dumble's personal touch in future models casts doubt on their authenticity. The amp's transparency might leave some players feeling exposed, but its legendary status and unique sound are undeniable, making it an experience worth savoring, even if it leaves you questioning your playing skills.

Under the microscope: Dumble Overdrive Special | MusicRadar

musicradar.com

The Dumble Overdrive Special is a rare gem in the world of guitar amplifiers, boasting a legacy that few can rival. Known for its clarity, power, and tonal versatility, it has become a prized possession among legendary musicians like Robben Ford. This amp is revered for its muscular tone and responsiveness, making it a dream for any guitarist seeking unparalleled sound quality. However, its exclusivity comes at a steep price, often exceeding £100,000, and its limited production means few will ever experience its magic firsthand. A must-have for tone purists, if you can afford it.
