OK so I love my SLO but the loop is hell. It worked OK with my G major 2 but I want to use my Stryman Time Line. So I found purely by accident the Lehle Paralell M. I received a coupon from Pro Guitar Shop that's only good for today so I was able to get $40.00 off. Anyway there is very little loss in signal quality if any and the Strymon sounds fantastic. Just set your device for kill dry or fully wet and your good to go. Anyway I thought I would share since I get great help from the forum all the time. I would think this would work well with a passive D style loop as well. PG has a $40.00 off coupon for anything over $249.00 so you can pick one up for $209.00 today.
