Hey guys, quick question. I was playing around with my new Fender 250 bassman amp today and discovered something strange. My effects (my EH Bassballs and Big Muff) sound great when put in straight through the amp, but they sound terrible when put through the effects loop. For example, when when using my bassballs in the loop, it sounds harsher and more crackly, almost like the signal is broken up. And with the Muff, you have to put the volume all the way up on the pedal in order to match your original signals. Could this be something with EH pedals, or is it just the effects loop in general?
