THE GTFO – full tube / high-gain/ high-voltage guitar overdrive


THE GTFO is the result of almost 4 years of experiments,testing and design. This high-gain overdrive was build to deliver the most authentic tube sound that a pedal can deliver.

The pedal is build using 2 x 12AX7 (ECC83) (NO solid-state elements in the audio path) tubes that are supplied with high voltage (300V) so, this is not a starved plate design and the tone that can deliver is a proof of this.

Inside, a DC-DC converter is used to boost the 12V DC supply voltage to 300V DC.

The pedal is delivered with JJ or TAD tubes and also with 12V @ 1.2A wall-wart so you can use it immediately in your pedal-board.

Another important feature is the small footprint (11 cm x 9.5 cm) so you can fit it in almost any pedal-board.

No simulations, no fakes, no compromises … just pure guitar TONE.

    I purchased the GTFO for its high gain capability, and it does not disappoint. This pedal will crush those chunky metal riffs. Looking forward to Dexter’s future projects, as well as bouncing any questions and ideas his way.

    I received, recently, GTFO from Dexter’s Workshop and it corresponds to all my expectations … Excellent design and realization. An exemplary service and fast answers to all the questions of the customers. Highly recommended!

    I have one of Dexter’s GTFO’s. It has a wide range from a clean od to a heavy od. Not sure what else to say other than it’s really fun pedal. I couldn’t be happier with it!
