Is it better to have the EQ before or after the stereo loop.
That's down to personal taste. I prefer the loop in x slot because the mod slot is stereo.
I.e. if you use a trem in x slot and a stereo loop in mod slot, your trem is going to be mono. If you change the order (loop in x, trem in mod slot), your trem is stereo Doesn't matter for eq though.
