Slightly related to this but probably a much easier fix, just I'm absolutely clueless at changing things around. I play a 5 string, but I'm looking change from B-G to E-C for more chordal and harmony stuff. Would there be much messing around with the bridge and the action to get a decent sound? Or is it just a case of figuring out which gauge strings will work best?
The only thing which might be an issue is the nut, sometimes the B slot can be cut low. You might also find the smaller strings move on the slots. Both of these would most likely mean a new nut is needed.
Other than that, if you like the tension of your current EADG strings, just go with the same sizes (105-85-65-45) is probably most common and you’ll keep roughly the same tension as B strings are usually sized light in commercial packs and when you put on the C it’ll probably be a 30 or 25 and in the same general tension area.
You will most likely need to make minor tweaks to the action and, after that, the intonation but it’s really not hard and there’s a wealth of information out there on how to do it.
