I put a set of EB Beefy Slinkys on my Donner. They’re made for a 4 string bass, 130/100/80/65. I had to open the nut a bit but luckily I have a set of very small files that took care of that. Set up was straight forward, no neck adjustments (as of yet) and only the B needed a slight tweak to intonation. I also bought a Rumble 100 ( current is a 25 ). Gotta say, that low string is pretty bad ass. Chevelle is a fav band of mine and most of their stuff is tuned low, B, C#, etc, which was my motivation to tinker. Now to practice, many of their songs are beyond my current ability.

That’s awesome, and here I am contemplating taking the B off my 5er and making it an E-A-D-G-C 5 string.

Just to try or are there songs you enjoy with that tuning?

2 of my 5 string are tune this way. It’s kinda cool

It is… but I find it hard to get good string sets for E-C. I hate having to buy a 6-string set and “toss” the B string - feels wrong

sorry to hijack the post, but what could be the repercussions to my 5 string if I were to use the existing strings and tuned them to E A D G C? Would it possibly damage the neck? Would the strings handle the stretch?
Probably not a good idea… I don’t think it is within the design specs of either the strings or the neck to use strings tuned UP a fifth 
Could be an interesting “experiment” if you had a spare set of strings and a spare bass (and saftey goggles)… personally, I would not recommend it!

I pulled up Stringjoy’s string tension calculator and you’re going from about 200lb of string tension to about 400 lbs. I’m not sure you can tune that much higher without breaking strings.
Even if you can fretting is probably going to be miserable because of the double tension.
