Here's what Cornerstone says about the Gladio SC:

Gladio SC (single channel), is designed to offer the same sound of the "big brother" Gladio but in a smaller and compact size.

While the Gladio double channel was inspire by the artists like Robben Ford and Sonny Landreth, the Gladio SC tries to take a step closer to the Steve Ray Vaughan sound, which was achieved using a Dumble amplifer too.

The Gladio SC is based on the Gladio 1st channel, with the exact same sound and controls, except the new CLEAN knob. This addition makes a very big difference, and it's the one that could actually make the sound be closer to SRV. The clean signal is taken directly at the input of the pedal and mixed back with the overdriven signal at the output, the CLEAN knob thus manages the volume of the clean signal with the result of having a "clean layer" on top of the overdrive sound, which helps a lot to achieve that Texas-blues sound.

A Clean knob like this affects 3 parameters all at once (you can notice their change sweeping the Clean from zero to even a 40% rotation):

  • Bottom End: The sound becomes fatter.
  • Compression: The non-compressed clean sound comes into the mix, and the change in compression is particularly accentuated on the attack.
  • Saturation: When the clean sound comes into the mix the final output sound becomes hotter, and it’s able to better push the front end of the amp.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
