Used Synergy Friedman Dirty Shirley Guitar Preamp

Used Synergy Friedman Dirty Shirley Guitar Preamp in great condition delivers the warm, vintage-inspired British crunch and rich cleans that made the Dirty Shirley a favorite. This all-tube Synergy module features two channels with independent Gain and Volume, plus shared EQ (Bass, Middle, Treble) and Presence for tight, punchy shaping. Designed for Synergy SYN-1/SYN-2 racks and heads, it responds like a real amp preamp with dynamic feel and sustain.
