Pedals that stack with the Boss AC-3

EarthQuaker Devices Hizumitas

Run EarthQuaker Devices Hizumitas into that transparent platform and it finally gets some high gain

Boss OD-1 Overdrive

Into a transparent tone, Boss OD-1 Overdrive brings the low gain it's missing

Walrus Audio Monument CS

Keep Walrus Audio Monument CS after Boss AC-3 in the signal chain, clear of Boss AC-3's own gain stage

Vox Valvenergy Silk Drive

Vox Valvenergy Silk Drive leans toward smooth, and that's a real, usable character to pair with

Alexander Pedals Now We Are Ghosts Reverb

Keep Boss AC-3's transparent voice out front: Alexander Pedals Now We Are Ghosts Reverb goes after Boss AC-3 in the signal chain so its analog warmth voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

Eventide Modulated Delay

Eventide Modulated Delay's modulated voice goes after Boss AC-3 in the signal chain — it's not there to compete with Boss AC-3's own transparent character — goes in the amp's FX loop (or last, into a clean amp)
