Pedals that stack with the Pigtronix OFM

Cordovox PH-8

Cordovox PH-8's modulated voice goes after Pigtronix OFM in the signal chain — it's not there to compete with Pigtronix OFM's own fuzzy character

Fender Blender

Fender Blender layers octave onto an already fuzzy signal

Walrus Audio Ages

Put Walrus Audio Ages in front and the fuzzy tone leans further toward clean boost

Strymon OB.1 Bass

What Strymon OB.1 Bass brings here leans toward clean boost — that's worth building a pairing around

Walrus Audio Mako D1 High-Fidelity Stereo Delay V1

Keep Walrus Audio Mako D1 High-Fidelity Stereo Delay V1 after Pigtronix OFM in the signal chain, clear of Pigtronix OFM's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Pigtronix Echolution

Keep Pigtronix OFM's fuzzy voice out front: Pigtronix Echolution goes after Pigtronix OFM in the signal chain so its modulated voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)
