The Malekko “E.FILTER” is part of the Malekko Omicron Series analog envelope filter pedal and saves you precious space on your pedalboard without sacrificing tone. Featuring the defining component in the most desired analog envelope filter pedals- the VTL5C2/4 vactrol, you get super rich sound in an unprecedented tiny enclosure at an affordable price. Small and simple to use, this true bypass pedal has two control pots: range and frequency. This pedal is capable of subtle mew to awesome deep cat screeching and everywhere in between. Runs off a ‘standard’ 9V-12VDC neg tip regulated power supply (not included). Current draw is 50mA. This pedal reacts better to super-hot pickups when a higher voltage power supply is used. Enclosure size approx. 3.6″x 1.5″x 1.2″.
