Silkworm Series 500 Preamplifier


If you are looking for a superior performance solid state preamp in series 500 format that covers all applications in a professional recording studio, look no further. This is your ticket.

Silkworm’s tone, versatility and reliability make it one of the finest this series has to offer. Mic input has a 3-position character (or vibe) switch, and output has a split personality, solid state or transformer driven. Depending on the setting, the sound can be anything between modern and vintage. Clean or somewhat colored.

Great sounding instrument input for direct recording of bass, guitars or keys. Gain is divided into 3 stages, and can be fine-trimmed within each stage. Of course all the standard features like pad, phase reversal and phantom voltage switches are also included.
