hope someone can help....running my pod hd 500 straight to front of amp which is a mesa nomad 55....i set a loop and try to play with it and it sounds horrible seems like no separation what so ever just a big glob of muffle...am i doing something wrong? the looper is in the very first spot of chain...plus i try to switch to another patch to get a boost to go over it and it just raises the volume of EVERYTHING....i loved the looper in my m13 i went to the effects loop of a different tube amp and had great results because i had recorded some practices of our three piece futzing around over a loop and it sounded killer...i ve had no luck with the hd 500 ...i m hoping its just a me being an imbecile....please help any suggestions welcome
