Browne Amplification Unit 13

The Browne Amplification Unit-13 has its roots in classic American distortion circuits, both loved and misunderstood by many. Like many things in life, the Unit-13 wasn’t something Browne necessarily planned to create. It slowly began
presenting itself through experiments, ideas, and the occasional late-night thought until we finally listened. The result is a dual overdrive/distortion with immense range, from subtle low-gain grit to an absolute sonic beating. Both sides of the Unit-13 share the same fundamental circuit, but each has been carefully tweaked and voiced for its intended role.

The left side is designed specifically as a low-gain stage. One of Brownes favorite ways to use classic distortion circuits is with the gain turned down, but doing so often sacrifices low end and leaves very little usable range on the Drive control. The Unit 13 therefore features expanded low-gain control: Browne reduced the total available gain, giving you far more control throughout the Drive knob’s sweep, and a 3-way Low End toggle which lets you dial back in the perfect amount of low end to suit your rig.

The right side takes the same core circuit in the opposite direction, voiced for classic higher-gain sounds and a more aggressive response. A 2-way Clipping Diode toggle selects between two different flavors of hard-clipping character.
