When it comes to pedals for acoustic guitars EQ's are top of the pile solely because no single guitar works perfectly for every stage/room. Sometimes you just need a bit more other times just a bit less in order to tame feedback and to help nail those pesky frequencies the Orange Acoustic pedal not only features a mid control but also allows you to focus the mids with an added Q range control and notch knob. A very helpful phase switch allows users to be heard no matter what rig or band they play with.
Its worth noting that these pedals don't always need to be a noise tamer, they can be used as effects themselves by making your small acoustic sound big and visa versa. and the ability to use them to create controlled feedback providing a pad style overtone is massive amounts of inspiring fun.
