The Cornerstone Nucleo Stereo Reverb is a signature ambient reverb pedal from the Italian boutique maker Cornerstone, developed in partnership with Dutch guitarist and YouTuber Paul Davids¹². Delicious Audio reported the pedal on July 29, 2025¹; Guitar.com and Guitar World had reported its pre-order in October 2024, with shipping slated for early December²³.

According to Delicious Audio, the pedal uses an M7 Cortex Engine to deliver three core reverb modes: Reactor (dense reflections), Room (intimate spaces) and Hall (expansive decays), each with Voicing options of Normal, Vintage and Lo-Fi¹. Three faders control modulation (MOD), pitch-shifting (ATR) and granular effects (FLUX)¹. A Freeze function captures infinite tails with pitch-adjustable freezing for pad-like layers¹.

The earlier reports describe a different control layout: two large dials for Reactor, which sets reverb size from a lo-fi room effect upward, and Blend, which sets the dry/wet balance, plus controls for Modulation, Pitch and Speed and dials for Decay, Tone and Freeze volume, with two footswitches for Bypass and Freeze²³. The pedal stores 3 onboard presets or 128 via MIDI, and has transformer-isolated stereo outputs and USB-C audio interface capability¹.

Guitar World reported that the pedal was available to pre-order at a launch price of $429, with orders shipping in early December³; Guitar.com gave the same price and a December launch². The Nucleo was inspired by Davids' visit to the Zwentendorf nuclear plant in Austria, which was never brought online after a change in public sentiment in 1978³.

Delicious Audio describes the pedal as extending beyond traditional reverb to cinematic textures and performative sound design¹. More on reverb pedals and the Cornerstone Nucleo.
