Add clean sustain to your guitar notes and chords with the CM-50 compressor pedal. Turning up the Sustain control squashes down the peaks in the signal and lifts the quieter parts, causing notes that are fading out to last longer with effortless sustain. Set the output with the Level control and adjust the amount of picking emphasis with the Attack control. Great for country licks and overlapping arpeggios.Power supply[tab]9V battery (PP3 included) or optional DC adaptor[br]Construction[tab]Aluminium housing with rubber base[br]Controls[tab]Sustain, Level and Attack[br]Dimensions[tab]115 x 68 x 47mm[br]Weight[tab]275g
