Valve Crystal 12AX7 Tube Preamp

PREAMP

The Valve Crystal is designed more like an amplifier than an effector. The amp model is the JM signature model that made TR-AMP famous. This original circuit is the clean channel of the legendary amplifier DUMBLE. Valve Crystal passes through the same integrated signal circuitry as your amp, delivering a gorgeous clean sound. Unlike many DUMBLE effects, this unit does not have a flashy drive sound. This is because many overdrives that use the Dumble name use TS or other overdrive circuits. It's just a Dumble sound the creator imagines.
