Plugin Alliance offers many top-notch plugins from manufacturers such as Dangerous Music, SPL, Elysia, Maag and Engl. Many (if not all) are developed by Brainworx and emulate analog hardware. Some are actual software originals, and a few are unlicensed emulations like the Mesa Boogie Dual Rectifier and the Boss Chorus pedal. Some of these are also offered on the UAD platform. Brainworx unfortunately (for us, not them) does exclusives for Universal Audio, which aren’t available through Plugin Alliance.
