kingmaker not quite as lush as expected

[skeeter]

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 on it the pdf rev2 what is the difference .I built the stacked BF2 from PedalPCB so this should have been easy .There isn''t much wooshing as you would expect maybe an input issue  but again what is the difference between rev1 and rev2
