heya, been trying to find out what the ideal gauge strings i would need for a 4 string drop B tuning (my band primarily covers slipknot) and i see the statement it needs a "full setup" but noone ever elaborates on this? what is it can i do it myself?

p.s i DO have a 5string and thats what i use but im going for a different sound thats on my 4 string

kabadi.man thanks for the reply, ill consider my options, what is actually the risk of using a 4 string for what im doing (worst case scenario)? will it physically damage my guitar? will it ruin the saddles or something?
