removing 80hz also lets you use the Ld1 Red mode (with the phat mod) because there is so much bass in that channel, you can cut it before it gets processed by the triaxis. thats only for pre-triaxis EQ tho. also, i really like how on the DEQ you can change the frequencies 0.5 db at a time tho. helps you to really fine tune the EQ settings. you are right also, about sounding worse when adding frequencies. when you cut the frequencies, you are removing the ones you dont want (which are the bad ones that makes your tone sound bad). if you boost the right frequences, you will be set, but im guessing you will end up with more cutting and less boosting. thats also why you are getting bad sounds out of it, because you are boosting the "bad" frequencies. again, this is where all the experimenting comes into play.
