Thats because Boss, Digitech etc don't make good pedals. DS-1 can be decent with a mod but any of the new Boss, Digitech etc designs sound utter rubbish
Given your taste for uber expensive PRS guitars and some very high end amps, what or earth would be you being with Digitech pedals in the first place ? lol
Check out some of the offering from MI Audio, Damage Control, Radial, etc if your seeking some quality distortion sounds.
