Yep, I moved to a 5-string about 7 years ago and there is no turning back. I can still play a 4 string when wanted/needed, but love the 5-string....going back to 4 string.
As the late George Burns would say (in another context); "I still remember how. I just don't remember why". And that's sort of how I feel about playing 4 string bass anymore.
Like others, when I first picked up a 5 string I felt like a fish out of water. My left hand was so confused. Perhaps I'm slow, but it took me a full 6 months to get to where I wasn't fumbling, a year I think, not to be in my head about 5 string. But here I am, approaching the two year mark and 5 string is home. I'll play my (one) 4 string occasionally as I did tonight. But now the 4 string feels odd, knowing that I could have that extra lower string, if only I'd put the 4 banger away and pick up any of my other basses.
As an extra, I've been fiddling with 6 string during the pandemic and got some relief of 3 outdoor summer performances where I did play my 6er for the first time at one of them. Going from 4 to 5 feels like it was more difficult than going from 5 to 6. I just needed to spend some quality time with the 6er, but it took only a week or two of practice to add the extra upper string. I supposed I'd have had a longer adaptation if I'd jumped from 4 to 6.
Anyway... I thought I'd share that for anyone contemplating making the jump to 5 string or might be hesitant to do it for some of the above reasons. All I can say is, if you've been thinking about it, now is the time. Why let a perfectly good pandemic go to waste?
A lot less movement required up-and-down the neck, easier to change keys on the fly, and the extended range is nice (especially the D on the B string, super fat). They are awesome, but not for everybody, and some of the greatest players of all-time did it on a 4 string
It did not take me long to adjust, but that was probably because I only played the 5-string, and also started on a fairly narrow 5'r neck, both probably helped me acclimate fast. I think too many people start out on a wide-ish 5-string neck which can just kill the experience. Still only want a 5-string with 1.75" nut and max 18mm bridge spacing (max). Thus the Stingray has been my favorite, along with my Roscoe 5, just perfect.
