Great shape! This rig will bring you sound to life! Simply UnbeatableAfter over 20 years of production the Demeter Amplification Tube Bass Preamplifier is still the only musical instrument preamplifier to incorporate truly modern tube design technology with circuit features found on only the most expensive and esoteric hi-fi tube equipment. The VTBPS has the warmth and dynamic range that only tubes can produce, yet has lower noise specifications than most solid state devices. When the preamplifier is driving a quality power amplifier, it delivers the punch and clarity of the best tube amplifiers plus the almost unlimited power of today's modern power amplifiers. Regulated DC is supplied to the tube filament which gives the unit extremely low noise. The VTBPS also has a low output impedance which lowers distortion and insures proper power amplifier input matching.
