Pedals that stack with the Donner Sustain

Marshall Guv'nor

Run Marshall Guv'nor into that transparent platform and it finally gets some mid-forward

Soldano SLO

Into a transparent tone, Soldano SLO brings the high gain it's missing

Boss RV-6 Reverb

Boss RV-6 Reverb's shimmer voice goes after Donner Sustain in the signal chain — it's not there to compete with Donner Sustain's own compressed character — goes in the amp's FX loop (or last, into a clean amp)

Catalinbread Cloak

Run Catalinbread Cloak after Donner Sustain in the signal chain, clear of Donner Sustain's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
