YESS! ANOTHER BIFFY FAN 😁😁😁
I love Biffy, and that's why I suggested the MD-2, cause I know that Simon Neil uses one. I know that he also uses an MT-2, or one of the Boss pedals of that ilk, and a DS-1. So you could have a look into those. The DS-1 is probably the one he used in Get ####ed Stud, but it could have been the MD-2, I can't really tell.
Mon the Biffy.
