Meris Polymoon

Keep HomeBrew Electronics CPR Compressor Retro's compressed voice out front: Meris Polymoon goes after HomeBrew Electronics CPR Compressor Retro 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)

Neunaber Wet Mono Reverb Pedal

Run Neunaber Wet Mono Reverb Pedal after HomeBrew Electronics CPR Compressor Retro in the signal chain, clear of HomeBrew Electronics CPR Compressor Retro's own gain stage — goes in the amp's FX loop (or last, into a clean amp)
