1 razzer10_4 2 weeks ago Are all effects loops the same? Here's why I ask. Until yesterday when my Crate Powerblock went wonky, I had what for me was a serviceable setup. The interface has stereo left and right outputs and the Crate's effects loop is labeled both send/return AND Line-In right and left. The wording in the manual basically states these inputs are dual purpose for both running an effects loop OR to run stereo cables. A lot of words but the basic question, is the Powerblock's effects loop inputs unique vs standard connections or do all effects loops basically perform the same tasks?
