Does anyone have any good information on EQ pedals? I'm trying to control and really dial in the tone from my Big Muff. I'd like it to be a single spaced stomp size with sliders. The only EQs I have come across are the GE-7 and the MXR 6 band. I haven't seen any boutique manufacturers doing anything with EQ pedals? Is this true? Any help would be really appreciated...thanks!
