Built the Kingmaker and can't quite get it to be as lush as the mxr or to get a little crazy the rate works well as does the manual ,the depth is ok and the feed back dosen''t quite work that well the MXR has a feed back trimmer ,my pcb has rev1 the pdf rev2 what is the difference .I built the stacked BF2 from PedalPCB so this should have been easy
