The Rocktron ValveSonic Black Plate + is a sophisticated four-tube guitar preamp, meticulously engineered to deliver unparalleled sonic versatility. It masterfully captures the iconic tones of classic American amplifiers, ranging from 50’s “Hybrid Tweed” to 60’s “Black Plate” panels. This unit further expands its capabilities by providing the sought-after hot-rodded sounds characteristic of classic California amps. Its innovative 1-2 input switch allows selection between modern "hot-rodded" or classic "Tweed" and "Black Face Panel" input types. The five-position BRIGHT control offers four distinct bright variations, enhancing tonal shaping. A comprehensive GAIN control, coupled with a switchable boost, enables precise drive adjustments and additional gain stages for California-style amplification. Dual EQ settings replicate either the 50's "Tweed" midrange emphasis or the 60's "Black Plate" panel response. The unique AFTERBURNER switch provides an additional post-EQ gain stage for further tonal saturation. A dedicated HIGH CUT control allows users to precisely manage high-frequency sizzle, ensuring optimal sound clarity. This single preamp unit offers a comprehensive solution for diverse guitar tonal requirements.
