The double Gladio returns.

The Cornerstone Gladio MK3 brings back the highly requested dual-channel Gladio concept, completely rebuilt from the ground up. Inspired by the D-style amplifiers behind Robben Ford and classic blues tones, both channels are designed to behave like preamps — responding naturally to your pick attack and guitar volume before anything else. 

Channel I delivers a transparent, highly dynamic response that moves from full clean to dirty depending on your playing attack. Channel II offers a more midrange-forward voice with harder clipping, now expanded with the new Ratio control, which blends the clean input signal in parallel with the overdrive to restore attack and definition without reducing gain. 

The MK3 also brings one of the most requested controls from the original Gladio to the front panel: Deep. Previously an internal trimpot, Deep now gives you direct control over the pedal’s low-end response. The channel order can also be reversed, while four audio jacks allow the Gladio MK3 to operate either as one dual-channel drive or as two completely independent pedals positioned anywhere in your signal chain.

Internally, a charge pump runs the circuit at 30V from a standard 9V DC power supply, providing cleaner transients and wider dynamic range. The MK3 is handmade in Italy and features a polished chrome enclosure, brushed metal plate and machined metal knobs with dual-colour anodising. Every unit is backed by a lifetime warranty and includes a certificate of authenticity with leather packaging.
