The Mooer Yellow Comp gives you compression as smooth as a stick of butter that this little pedal resembles. Classic optical compression with a super-smooth attack and decay help to preserve your tone and the dynamics of your transients are all par for the course with this micropedal. Volume, EQ, and Comp all give you the ultimate control over your compression so you never have to worry about being too squashed or to jarring - whatever you want your sound to be, you can get it with this tiny pedal.
