I know there currently isnt a Metal Muff on the Helix (Line 6 hint hint please) but is there any recommendations to get close to the effect of one on teh Helix, i know the Big Muff is on there, and that's probably what i'd have to use in the end but just wanted to see if anyone out there has experimented with anything else to try and achieve the effect of the Metal Muff, thanks in advance to any who decided to chime in \m/
