Compressor Pedals control the dynamic range of your tone while increasing sustain & thickness. Compressors make overall level of your playing consistent.

Guitar compressors are traditionally popular with country players, but are seen in a wide range of genres like Funk & Blues. Standout compressor pedals include the affordable Caline CP47 Pressure Tank, versatile MXR M102 Dyna Comp.
