Flatwound Drop-tuning question

[Fionn]

I use light gauge (40-60-70-95) Ernie Ball Cobalt Flats on all my basses. This gauge/ tension is perfect for me.

I’d like to drop tune one of my basses to C-F-A#-D# (standard 34” scale).

I love the specific character of the EB Cobalt flats, so I’d like to stick to this brand.

I can’t use their 5-string set as their only available gauge is too high. Their heaviest 4-string set is 55-75-90-110. I wonder how this set would work at that tuning? Specifically, would the 110 go down to C without losing definition?

I reckon I could live with that tension.

Are there any other factors that I’m failing to consider here? I could switch brand and put the low-4 of a light gauge 5-string set on there, but I’d rather not. There’s no string like the EB cobalt flats.

Just wondering what I can get away with, tuning down that heavy set.

What do you reckon?

I reckon you could get away with that.

I use a 105 gauge for drop D and it sounds good.

I use the 45-100 set and have a drop D tuner, sounds and feels fine.

Ernie Ball do single strings - https://www.ernieball.com/guitar-strings/bass-strings/bass-single-strings/slinky-flatwound-electric-bass-single-strings#P10855

 

If you contacted them with your problem they may be able to suggest a balanced set for the tuning/tension you want.

I use a 110 E string so that I can tune down to B when I need it. I need to exercise some self restraint when tuning down to the B as it does get a tad floppy ( I use a 130 B string when playing 5s ) but if you are using a light gauge to begin with then you should get away using a 110 tuned to C
