Essential Information About the Cornerstone Gladio SC Pedal
Essential Information About the Cornerstone Gladio SC Pedal
- Overdrive / D-Style Preamp: an "amp-like" response designed to capture the singing, dynamic, and harmonic grain of Dumble-inspired tones, without losing the feel of playing through a real amp channel.
- Exclusive Clean Control: reinjects clean signal over the drive to maintain attack, definition, and articulation, particularly effective for punchy rhythms and "Texas blues" style phrasing.
- 2-Position COMP Switch: choose between a more open and percussive overdrive or a more compressed response with increased sustain for leads that need to stand out.
- Compact format, top-mounted jacks, true bypass: easy integration on pedalboards and careful craftsmanship, in the spirit of modern boutique pedals.

Gladio SC: The Spirit of the First Channel with a More "Texas" Approach
The Cornerstone Gladio SC (Single Channel) is part of a well-known quest among guitarists: to capture, in pedal format, the touch and richness of an overdrive inspired by Dumble amplifiers. While many D-Style pedals focus mainly on thickness and warmth, the Gladio SC also seeks the percussive and lively side of a more upfront blues playing style.Within the Gladio range, this SC version carries the DNA of the first channel of the dual Gladio, but in a more compact enclosure and with an ingredient that truly changes the feel: the Clean potentiometer. The idea is not just to add clarity but to preserve the "backbone" of the sound (attack, string, transients) that makes an overdrive respond like an amp when you vary your pick attack or guitar volume.
Who the Gladio SC Is For: From Expressive Blues to Vintage Rock
The Gladio SC is designed for guitarists who want a responsive and nuanced overdrive, capable of moving from a slight "edge of breakup" to a more present drive without muddying chords. It suits both intermediate players looking for an inspiring and easy-to-set pedal and advanced guitarists wanting a high-end, stable, and musically coherent tone foundation from one backline to another.Its natural playground: blues, Texas blues, vintage rock, fusion, roots pop, and more broadly any style where you want a warm but articulate drive. Live, it excels on an amp set fairly clean (clear platform): you build your tone with your foot, then maintain control with your right hand. In the studio, its "preamp" character helps lay down full and clear rhythms, then bring out a lead by boosting the level or switching to a more singing compression via the COMP switch.

Questions frequently asked
Is the Cornerstone Gladio SC suitable for single-coil and humbucker pickups?
Its Tone control allows adjusting the drive's brightness to fit both single-coil and humbucker pickups. With single-coils, the Clean boosts the attack; with humbuckers, the pedal provides sustain without muddying the low end.
What is the purpose of the Clean potentiometer on this overdrive?
The Clean potentiometer reintroduces attack and definition into the saturated signal. This keeps chords clearer even with a high Gain setting.
What kind of sound does this pedal offer for Texas blues?
The analog saturation leans towards a warm, articulate tone rich in harmonics. The blend of drive and Clean signal favors a percussive playing style, suited to Texas blues approaches and referenced players such as Robben Ford or Stevie Ray Vaughan. The COMP switch provides two compression levels for either an open response or a smoother sustain.
What power supply is required for the Gladio SC?
A 9 V DC center-negative power supply with a 5.5 x 2.1 mm connector is required. The stated current consumption is 42 mA and battery operation is not supported.
Can the Gladio SC be used as a boost for solos?
The Volume potentiometer adjusts the overall level or can boost the signal sent to the amp input. The pedal features a 6.35 mm jack input and output, as well as an effects bypass.
