A hand-built, point-to-point wired guitar amplifier designed in collaboration with Butch Walker and built in Divided by Thirteen’s California factory.

It features two independent tube power sections that can be run individually or combined, delivering 17 watts from an EL84 cathode-biased section, 40 watts from a 6L6 fixed-bias section, or a combined output of 57 watts when both are engaged.

A six-position input gain selector provides intentional front-end voicing changes rather than simple gain increases, while a treble control with push-pull Bright switch and a fully tube-buffered effects loop with defeat and Bright option offer practical flexibility without complicating the signal path.
Introducing 

The Divided by Thirteen x Celestion 454 Speaker

• A proprietary 12-inch, 40-watt guitar speaker built by Celestion in their UK factory.
• It retains the familiar midrange response, natural compression, and musical breakup associated with a classic Greenback, while offering increased power handling for broader use across Divided by Thirteen amplifiers and cabinet configurations.
• The result is a balanced, adaptable speaker that feels familiar under the fingers but remains stable and reliable in higher-power and multi-speaker applications
