Ein Alleskönner Boost? Jein! Ein Always-on Pedal? Vielleicht! Das Zio klingt jedenfalls immer richtig gut. Vor meinem Bogner Ecstasy hat es eine weniger gute Figur gemacht als vor dem Soldano SLO. Dort aber so richtig. Clean mit E-Plex Circuit und Verzerrt als Bass-Zähmer tut es, was es soll. Da rauscht nix und das Pedal ist mega hochwertig verarbeitet. Zudem angenehm kompakt. Kann man nur empfehlen!
