Best Alternatives to the MXR Dyna Comp

Two knobs, unambiguous character — the Sensitivity squish and Output makeup gain that define country chicken-picking, funk rhythm, and SRV-style sustain boost. Used by Mark Knopfler, Brad Paisley, and Nile Rodgers; the Dyna Comp's coloured compression has become a genre-defining effect rather than merely a utility pedal.
