Rough Rider by Audio Damage

Rough Rider is a modern compressor with a bit of “vintage” style bite and a uniquely warm sound. Perfect for adding compression effects to your drum buss, it also sounds great with synth bass, clean guitar, and backing vocals. Definitely not an all-purpose compressor, Rough Rider is at its best when used to add a pump to rhythmic tracks.
