Pedals that stack with the Keeley Octa Psi

Electro-Harmonix Crayon

What Electro-Harmonix Crayon brings here leans toward transparent — that's worth building a pairing around

Ibanez Pentatone Preamp

Ibanez Pentatone Preamp's own saturated character is the real reason this is worth trying

Walrus Audio Julia

Ashdown Macchiato Compressor Guy Pratt Signature

Ashdown Macchiato Compressor Guy Pratt Signature leans toward compressed, and that's a real, usable character to pair with

Alexander Pedals Radical Delay

Put Alexander Pedals Radical Delay after Keeley Octa Psi in the signal chain, clear of Keeley Octa Psi's own gain stage — goes in the amp's FX loop (or last, into a clean amp)

Caroline Guitar Company Meteore

Caroline Guitar Company Meteore's pristine voice goes after Keeley Octa Psi in the signal chain — it's not there to compete with Keeley Octa Psi's own octave character — goes in the amp's FX loop (or last, into a clean amp)
