I use this

they are nice for guitars like my Schecter E/A 6.
you can dial the exact mix easy, and yes it has boost cut.
cool item and plugs right in to the 11r and works perfect.
clean or some drive!!
works nice on the 12 string I have too with the 2 pickup setup.
bridge and inside mics... you can balance them perfect!!
