Up for sale is my Cornerstone Gladio (2.1 Double Preamp) in mint condition — Cornerstone's flagship dual-channel Dumble-style overdrive/preamp that started the whole "boutique Dumble pedal" wave when it launched in 2020.

Why it's special:

• Two independent, totally different-voiced channels in one pedal for serious tonal range
• Channel 1: smooth, creamy, touch-sensitive tone inspired by Robben Ford's playing, with Gain, Tone, and Volume controls plus a COMP toggle for two compression levels
• Channel 2: a harder-clipping, more aggressive voice inspired by Sonny Landreth, with its own controls and a JAZZ/ROCK toggle
• Special S/D switching mode: "Single" lets you use one channel at a time (no accidental double-triggering), "Double" lets you stack both channels into one huge, fat Dumble-esque tone
• Realistic tube-compression behavior designed to mimic a genuine Dumble preamp's saturation while staying touch-responsive
• Standard 9V DC power, easy to fit on any board

Condition: Mint. No scratches, marks, or signs of use anywhere on the enclosure. All knobs, switches, and footswitches feel and function like new. Fully tested and working perfectly. Velcro is already applied to the back, so it's ready to drop straight onto a pedalboard. Smoke-free home.

If you've been chasing that elusive Dumble tone with real channel-stacking versatility — Robben Ford smoothness on one side, Sonny Landreth grit on the other — this is one of the best boutique options out there. Fast, secure shipping.
