Up for grabs is a FEA Labs Growler. I'm also including the 3 way TRS cable in case anyone wants to use the effects loop. The pedal generates synthetic even order harmonics. It is made mostly to thicken your tone and make low notes more audible. You can read more about it and hear sound samples on the manufacturer's page: http://www.fealabs.com/products/GROWLER-0001.html It has sadly been discontinued, and I'm finding it a little redundant/"excessive"on my 12 string bass, but it can do wonders for regular 4 and 5 strings, and the pedal name is pretty apt on certain settings. I'm asking $120, which includes the cable and cost of shipping within the ContUS. Not looking for any trades except maybe a Source Audio BEFPro.
