This may have been discussed before but has anyone used/currently use an FX Loop Blend pedal for their FX? I mainly want to use it with my OD pedals so I can use almost any OD pedal and bring back the low end by mixing in some of the dry signal as well. I have a Line 6 M13 and I can throw this into that FX loop and only have certain Fx from the Line 6 (Dirts) through the blender and have the rest be full on since most mods and delays have a mix knob anyway. This is the one I am looking at. What are your experiences with blend pedals?
