Hello All, Well alright...I know it's been asked many times and I did the search. but I want to find out why the equations are not explained in a more technical matter than just..." I can do anything on a 34 that you can do on a 35...boy.. which I see here alot. My main quest for knowledge here about the subject is because of jumping the fence from a 4 to a 5 string. But I read here somewhere that to get more precise intonation of the " B " string it's required to have a 35 scale length neck on the 5 string bass. That was not discussed thoroughly in a technical standpoint for me to run out and purchase a 35 scale bass only. If a seasoned player with mature knowledge of this delusion can honestly say it matters please let me know too. I always played 4 bangers for many years now and I would like to switch to the 5 but I need your advise , since I don't know much about it.
