If you’re a modern-style player who demands a classic rock tone, dripping with juicy harmonics, you’ll want to plug into the Synergy Friedman DS preamp. While some preamps seek to emulate or model a particular amplifier’s tone, the DS has been carefully designed by none other than Dave Friedman to nail the exact tone and feel of his Dirty Shirley amps. In fact, the DS module’s two 12AX7-powered channels offer even more versatility than Friedman’s original tube head. Dial one channel in with a bit of grit while the other is driven into a luscious lead tone, and it’s like having two Dirty Shirleys at your beck and call. Install the Synergy Friedman DS Preamp and dive into Dave Friedman’s take on the ideal vintage guitar tone.
The Synergy DS pre-amp features two channels each with knobs for gain and volume and a bright switch. Both channels share a three band EQ.
