Can’t go back to playing a 4 string

My first ride-or-die bass was my fender 4 string jazz bass. I loved that bass and used it for 5 years. Then I got a squier 5 string jazz bass which I’ve modded (new bridge and tuners) and even had the action set perfect on it. Now I can’t go back to playing my fender, but I can’t get rid of it either because the bass is too sentimental to get rid of.

Any suggestions on what to do would be much appreciated 🙏
