Groove Tubes ViPRE Variable Impedance All-Tube Microphone Preamp

The Groove Tubes ViPRE is a remarkable piece of boutique analog recording gear: a single-channel, Class A, all-tube microphone preamplifier designed by Aspen Pittman with unusually flexible control over the sound of your microphone. Its variable input impedance and selectable rise-time settings let you explore everything from warm, rounded vintage character to faster, more detailed transients, without reaching for an EQ. Four selectable microphone input impedances (300, 600, 1,200, and 2,400 ohms) make the ViPRE especially fascinating with ribbon microphones, but it is equally rewarding with dynamic and condenser microphones. Fully floating differential input and output circuitry, carefully stepped gain adjustments, substantial headroom, and detailed metering make it a distinctive high-end recording front end. There's also a front-panel instrument input, making the ViPRE an exciting option for direct-recording bass and other instruments. Its substantial all-tube design brings a tactile, hands-on experience that feels very different from ordinary modern microphone preamps. This ViPRE has been used exclusively in my smoke-free recording studio and has been carefully cared for. It's hardly been used since the last time the tubes were replaced. I'm selling it as part of the sale of my studio equipment. It is in excellent condition. If you appreciate the character and flexibility of a truly distinctive microphone preamp, the ViPRE is worth serious consideration.
