About this listing
The Groove Tubes ViPre (Variable Impedance Preamplifier) is a legendary, over-engineered single-channel Class-A tube preamp designed by Aspen Pittman. Famous for its robust, all-tube design, it delivers up to 75dB of gain and features highly customizable tone-shaping controls, including variable input impedance and slew-rate (rise time) adjustment.Variable Input Impedance: Allows precise impedance matching (300, 600, 1200, and 2400 ohms) to optimize the transient response and frequency character of any microphone, especially vintage ribbons.Rise Time Control: A unique feature that adjusts the slew rate of the vacuum tubes, letting users dial in sounds ranging from slower, vintage warmth to faster, modern crispness.Precision Gain Stages: Employs two rotary knobs (a 5 dB stepped initial gain and a 1 dB stepped attenuator) ensuring highly precise and repeatable settings.Design & Build: Features a fully differential, floated signal path that utilizes twice the number of tubes as standard preamps for exceptional common-mode rejection.
