Cornerstone Nucleo Paul David Signature Reverb Pedal

The Cornerstone Nucleo is not just a reverb pedal — it’s a universe of textures designed to inspire creativity and exploration. Developed in collaboration with Paul Davids and featuring the powerful M7 Cortex Engine, Nucleo delivers everything from subtle ambience to vast, cinematic soundscapes. Every nuance was crafted to create evolving, organic reverb tones that respond dynamically to your playing.

At its core, Nucleo features three reverb modes — Reactor, Room, and Hall — each with distinct character and depth. These can be further shaped with three voicings: Normal, Vintage, and Lo-Fi, allowing instant tonal transformation. The real magic lies in the three expressive faders — MOD, AIR, and FLUX — which add modulation, pitch shifting, and granular movement, unlocking limitless creative potential.

A built-in Freeze section lets you sustain reverb tails indefinitely, transforming your signal into pads or ambient layers, while Freeze Pitch allows pitch-shifting of the held sound for smooth, atmospheric transitions.

Designed for both studio and stage, Nucleo includes TRS inputs for mono or stereo use and transformer-isolated stereo outputs for crystal-clear, noise-free performance. It also doubles as a USB audio interface, making it perfect for recording and experimentation straight from your pedalboard. With 3 onboard presets and MIDI support for up to 128 presets, Nucleo offers instant recall of your most inspiring soundscapes.
