Thinking about getting a DOD Meat Box or one of the clones from Mantic, like the Beef Bag or maybe even the Density Hulk. My question is, how well do these sub pedals combine with dirt pedals like overdrive/distortion/fuzz? Also, I've heard these sub pedals can be dangerouse on speakers, so would combining them with dirt amplifiy the possibility of damaging speakers? I always play with my Fuzzrocious Demon as an always on pedal and most of the time I combine it with my Rat Tail or Grey Stache, so it is kind of crucial for me that these sub pedals combine well with my dirt. Thanks in advance.
