The JHS Double Barrel V4 is a dual overdrive featuring circuits from two of JHS's most popular pedals - the Morning Glory and the Moonshine. The right half of the pedal is the Moonshine, and the little green LED should tip you off as to which overdrive circuit it's based on. The left side houses the Morning Glory, which has a blue LED and is based on a popular overdrive circuit that is in turn based on a popular amp of the same name. This particular Double Barrel has had one owner, was never gigged with, and comes with the original box. It is in excellent condition.
