The Friedman Sir-Compre is an optical compressor pedal packed with tone shaping and a bit of subtle overdrive. With the signature squeeze of optical gain reduction, Friedman's unique "Tight" control and a huge gain range that goes from pristine cleans to ticked-off drive sounds, the Sir-Compre shapes your overall sound to your heart's content and is immensely powerful for beefing up your amp's clean channel.
