I bought an Ibanez srx 5 and it was so wide that it was painful to play. I gave up on 5s
then I bought a sire v7/5 which is very tightly spaced and it is almost capable of playing itself.
my philosophy for 5 is this:
1. don’t try and use the b
2. if something can be played more easily using the B above fret 4 then do it. There are no prizes for making your life harder, suffering is not a virtue
3. avoid open strings by using the B - no open E, play across from
B, fret 5
you have to know what you want from your 5 in order to be able to get its best value
