Pedals that stack with the Pigtronix Space Rip Pwm Synth

Xotic RC Booster

Xotic RC Booster leans toward transparent, and that's a real, usable character to pair with

Beetronics Buzzter Boost Preamp

Beetronics Buzzter Boost Preamp's own transparent character is the real reason this is worth trying

Electro-Harmonix Canyon

Put Electro-Harmonix Canyon after Pigtronix Space Rip Pwm Synth in the signal chain, clear of Pigtronix Space Rip Pwm Synth's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Empress Echosystem

Empress Echosystem's pristine voice goes after Pigtronix Space Rip Pwm Synth in the signal chain — it's not there to compete with Pigtronix Space Rip Pwm Synth's own modulated character — goes in the amp's FX loop (or last, into a clean amp)
