I'm currently looking into streamlining my live setup for a new noisy grindcore influenced project. It'll be 1 guitarist, 1 singer, 1 laptop drum machine. I wanna travel as light as possible so I'm thinking about completely ditching my amp and cab and going direct to the PA from my effects chain. I'm not interested in "authentic" sounding guitar tones, I just want it harsh with plenty of bottom end action... (just like what yo mama told me last night...) I've been looking at either multi fx with cab sim for DI (eg. a line 6 HD500/Helix), or pedal board with a preamp (eg. Randall RG13) and a cab sim DI box (H&K Red Box). Would I even need a preamp or just a distortion pedal and cab sim? Does anybody else do anything like this? Or am I completely insane?
