The pedal aims to capture Dumble-style tones and is modeled after four generations of Overdrive Special amps.

Oakland, CA (July 13, 2018) -- Vertex Effects announces the release of their highly anticipated Ultraphonix Overdrive. Ultraphonix underwent a four-year R&D process, using four generations of Dumble Overdrive Special amplifiers to accurately re-create the iconic D-style tone. Watch their YouTube video (below) showing a Dumble amp versus the Ultraphonix pedal to see similarities. Ultraphonix is equipped with a lifetime warranty, built in a rugged steel enclosure with quintessential D-style appointments. If you’re looking for the most sonically correct D-style overdrive pedal, look no further with this 100% analog stompbox for a price tag that won’t require you to re-mortgage your house.

Ultraphonix features include:

  • 100% Analog D-style Overdrive Emulator
  • Volume, Filter, and Gain Controls
  • Top-Mounted Jacks (input, output, 9VDC)
  • 9VDC Power (standard polarity)
  • True Bypass
  • Lifetime Warranty

Ultraphonix retails for $199.99

An overachieving overdrive that gets way bigger than its name suggests.

Sweet balanced crunch tones. Dynamic. Sparkling, full, and clean at attenuated guitar volume. High-quality build.

Pretty expensive.


Great Eastern FX Small Speaker Overdrive


Overdrive pedals don’t often set my world alight—even great ones. But I’ve spent a month with the England-built Great Eastern FX Small Speaker Overdrive, and it remains attached to the other end of my coil-y cable. Ostensibly, the Small Speaker is meant to be a variation on the tweed-Fender-Champ-in-a-box theme. However, both the pedal’s name and the Champ associations fail to do justice to how large and alive it sounds and feels tethered to a bigger amp.
