Cornerstone Gladio Preamp

The Cornerstone Gladio Preamp brings legendary D-style tone straight to your pedalboard—now available at Rhythmic Restorations. Inspired by the dynamic, touch-sensitive response of classic boutique amps, the Gladio delivers rich, harmonically complex overdrive that feels as good as it sounds.

Designed with two fully independent channels, this preamp gives you incredible flexibility. Channel 1 offers smooth, transparent low-gain drive that enhances your core tone, while Channel 2 adds thicker, more saturated overdrive with singing sustain. Stack them together and you unlock a wide range of expressive tones—from subtle breakup to full-on lead voice.

The Gladio’s strength is in its feel—highly responsive to pick attack and guitar volume, making it perfect for players who live in the nuances. With intuitive controls and premium build quality, it integrates seamlessly into any rig whether you’re running direct, into a power amp, or in front of a clean platform.

For players chasing that elusive, touch-sensitive boutique overdrive, the Cornerstone Gladio Preamp delivers in a big way.
