I followed the info I've seen on this forum and some others and videos to remove the leftmost wire from the mix pot and isolate it and move the rightmost wire to the center point along with the wire currently in place but it didn't seem to do the trick. I still had the phasing but lower volume and it was very thin sounding so I put it back to normal. Attached is a photo. What did I do wrong? I asked Mesa but they sent me the usual electrical diagram but I'm a layman, don't understand it all.
