Cornerstone Gladio Preamp/Overdrive Pedal

The Cornerstone Gladio is a boutique overdrive/preamp pedal inspired by legendary Dumble tones, like those of Robben Ford. It delivers a transparent, touch-sensitive drive with crisp compression and warm, singing clarity—perfect for achieving authentic Texas blues overdrive at low-to-medium gain. Available in both dual-channel and compact single-channel versions, it offers versatile tone-shaping for expressive, dynamic playing.
