Pedals that stack with the AmpRx BrownBox

Dallas Rangemaster Treble Booster

The Rangemaster's germanium treble boost stacks with the BrownBox's own transformer-driven harmonic lift for a richer, brown-sound push.

MXR Distortion+

The Distortion+'s gritty, compressed clipping gives the BrownBox's transformer-driven harmonic lift somewhere heavier to land.

Hughes & Kettner Tube Rotosphere MKII The Analog Leslie Simulator

Run the Rotosphere's Leslie-style swirl after the BrownBox's own harmonic transformer boost settles, so the modulation moves a defined tone.

Ashdown Studio Compressor

Run the Studio Compressor's low-noise compression ahead of the BrownBox for even dynamics before the transformer-driven harmonic boost reacts.

Roland SDE-3000D

Keep the SDE-3000D's modern digital delay trailing after the BrownBox's harmonic transformer boost, not before, or the repeats inherit an unshaped tone. — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Mako D1 High-Fidelity Stereo Delay V1

Keep the Mako D1's platform-voiced digital delay trailing after the BrownBox's harmonic boost, not before, or the repeats inherit an unshaped tone. — goes in the amp's FX loop (or last, into a clean amp)
