Pedals that stack with the CostaLab Buffer

Beetronics Nectar

Beetronics Nectar's low gain fills in what this transparent tone doesn't make on its own

Walrus Audio Eons

Into a transparent tone, Walrus Audio Eons brings the low gain it's missing

Neunaber Wet Mono Reverb Pedal

Keep Neunaber Wet Mono Reverb Pedal after CostaLab Buffer in the signal chain, clear of CostaLab Buffer's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Meris Polymoon

Keep CostaLab Buffer's transparent voice out front: Meris Polymoon goes after CostaLab Buffer 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)
