A more compact version of the beloved Cornerstone Gladio!
The original Cornestone Gladio, a two-channel Dumble-style overdrive pedal, took the guitar community by storm in 2020.
The Gladio SC (single channel) is designed to offer the same sound as its big brother, but in a smaller, more compact format.
The Gladio SC is based on the Gladio's 1st channel and features the exact same sound and controls.
Cornerstone added a Clean knob to the design, making it easier than ever to capture classic Stevie Ray Vaughan tones.
Clean signal at the input is mixed back in with the overdriven signal at the output, adding a 'clean layer' on top of the overdriven sound.
Raising the Clean knob results in fatter, more open tones. Pushing the front end of your amp also becomes much easier.
While the Gladio takes inspiration from Robben Ford and Sonny Landreth, the Gladio SC is all about SRV's classic Dumble tones!
Cornerstone Gladio SC overdrive features:
• Dumble-style overdrive.
• Capture classic Stevie Ray Vaughan tones!
• Clean knob adds a 'clean layer' on top of the overdriven sound.
• Power: 9V DC.
• Current Draw: Less than 100mA.
• Dimensions: 1.34" x 4.72" x 1.57".
