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. \u003c\/p\u003e\n\u003cp class=\"p1\"\u003eChannel 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. \u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eInternally, 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.\u003c\/p\u003e\n\u003cp class=\"p3\"\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual-channel D-style overdrive\/preamp\u003c\/li\u003e\n\u003cli\u003eChannel I: transparent and highly dynamic drive\u003c\/li\u003e\n\u003cli\u003eChannel II: midrange-forward voice with harder clipping\u003c\/li\u003e\n\u003cli\u003eIndependent Volume, Gain, Tone and Comp controls per channel\u003c\/li\u003e\n\u003cli\u003eRatio control on Channel II for parallel clean blending\u003c\/li\u003e\n\u003cli\u003eExternal Deep control for low-end adjustment\u003c\/li\u003e\n\u003cli\u003eSwitchable Channel I → II \/ Channel II → I order\u003c\/li\u003e\n\u003cli\u003eFour-jack configuration for independent channel routing\u003c\/li\u003e\n\u003cli\u003eRemote mini-jack for a latching stereo footswitch\u003c\/li\u003e\n\u003cli\u003eInternal 30V operation for increased headroom and dynamic range\u003c\/li\u003e\n\u003cli\u003eRuns from a standard 9V DC centre-negative power supply\u003c\/li\u003e\n\u003cli\u003ePolished chrome enclosure with brushed metal plate\u003c\/li\u003e\n\u003cli\u003eMachined metal knobs with dual-colour anodising\u003c\/li\u003e\n\u003cli\u003eHandmade in Italy\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncludes certificate of authenticity\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cornerstone","offers":[{"title":"Default Title","offer_id":41657575112762,"sku":"Cornesrtone-Gladio-MK3","price":497.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1764\/4443\/files\/1th_Screenshot2026-09-17at11.59.04am_9f668fb4-9e89-4922-a2e6-c89fe304526b.jpg?v=1789610549","url":"https:\/\/gsus4.com.au\/en-us\/products\/cornerstone-gladio-mk3-dual-preamp-overdrive-based-on-dumble-amp","provider":"Gsus4","version":"1.0","type":"link"}
