Hi, just curious, are you using a Stage or a toaster(or rack)? I ask this offline so not to create a shitshow. I have both the stage and toaster.My stage does not produce the sub bass but the toaster does........... I profiled the same amp (EVH 50wt w suhr rlir) Ive been using the same stuff for years and just recently noticed the huge sub bass on the palm mutes.
