Offering a double helping of rich analog overdrive channels, the Vahlbruch Jewel Drive runs the spectrum of warm tube amp tone. A streamlined layout of Drive, Volume, and Treble controls get you tones from thick Tweed presence to a transparent crunchy breakup out of the gate, and an added Timbre knob sculpts the midrange, dynamics, and overtones all with a single turn. Hand built in Germany, the Jewel Drive is essentially decades of amp tone in one boutique box.
