Pedals that stack with the MXR CSP204 Custom Comp Deluxe

Beetronics Overhive

Into a transparent tone, Beetronics Overhive brings the medium gain it's missing

Beetronics Nectar

Run Beetronics Nectar into that transparent platform and it finally gets some low gain

Meris Polymoon

Meris Polymoon's modulated voice goes after MXR CSP204 Custom Comp Deluxe in the signal chain — it's not there to compete with MXR CSP204 Custom Comp Deluxe's own transparent character — goes in the amp's FX loop (or last, into a clean amp)

Neunaber Wet Mono Reverb Pedal

Put Neunaber Wet Mono Reverb Pedal after MXR CSP204 Custom Comp Deluxe in the signal chain, clear of MXR CSP204 Custom Comp Deluxe's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
