I have a Helix and want to use my Dunlop MC404 CAE Wah Pedal as it, for me, is so very versatile and gives pure wah tone. I have it set up as a line input (was much noisier with instrument input), mono send and return on the effects chain. I know with a regular amp set up I would connect : guitar > wah > amp input. However I use the wah with both a Les Paul and a Variax so I would have use the send and return method. My question is where in the effects chain should I place it? When I place it first there is a LOT of line noise which I have use a noise suppressor immediately afterwards to tame it. Even with that the wah still doesn't sound like a real wah even though it clearly is!! Any and all suggestions to help are welcome. Thanks.
