A lot of people use more than 1 eq pedal, at various positions in their chain. So you don't have to limit yourself (and your imagination) to one.
I wanted to write "although in the short term you might have to"; but I didn't want to make any assumptions
its cool waise...since i only use one dirt box(the bd-2 and soon to be replaced with the sansamp) it works out pretty well for me. i suppose i COULD use one after the guitar too but yes, thats for later
