I believe this is a very rare, early model of the 9 Overdrive, Verre. The sound is outstanding, with excellent separation and a unique distortion with a crisp attack. The shimmering distortion, like shattered glass, is unlike anything I've heard before, and it's incredibly pleasant without being harsh. It's amazing. Used as a booster in front of a heavy distortion pedal, it adds separation and clarity, elevating your sound. As a crunch or overdrive, it provides excellent pick attack response, resulting in a supremely satisfying sound. Please consider it. #boss #boss #zoom #zoom #Line6 #kemper #fractal #multieffects #ampsim #ampsimulator #digitalamp #pedal #compacteffectspedal #distortion #distortionpedal #dumble #TS #centaur #analog #vacuumtube
