Originally released in the 80's, the Micro Flanger is a more compact, simplified version of the M117R below. This faithful recreation features 100% analog bucket brigade technology for the ultimate in warm and organic tone. Go from jet plane like resonance sweeps to cool outer space type flange with two simple rate and regen controls. Updated with a true bypass switch so there’s no loss of tone before you hit that switch for take-off! Sounds great with guitar or bass. True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003).
