Pedals that stack with the Death By Audio Moonbeam

Beetronics Overhive

Push the Overhive's transparent drive into the Moonbeam's phaser and its psychedelic swirl gets a stronger signal to work with.

ProCo RAT 2

Run the RAT2's gritty, low-gain distortion ahead of the Moonbeam so the stereo phasing swirls over an already-saturated tone.

Electro-Harmonix XO Deluxe Memory Man

Run the Memory Man's lush analog echo after the Moonbeam's experimental, boutique phase sweep and the repeats carry that swirl forward. — goes in the amp's FX loop (or last, into a clean amp)

Boss RV-5 Digital Reverb

Run the RV-5's spring-style reverb after the Moonbeam's stereo phaser sweep, so the wash trails the modulation instead of blurring it. — goes in the amp's FX loop (or last, into a clean amp)
