I played a 4 string a couple of weeks ago for the first time in over a year since making the switch to 5. There were a bunch of musos at the gig with a possibility of someone else getting up, so I took something that wouldn't confuse them too much. It turned out that the only other bass player to get up was left-handed anyway and brought their Hofner violin bass with them 😁
Still, it was quite interesting to switch back for a night after my 15 month "immersion" in the land of 5
Oh, and I thought this thread was about 5 strings being a bit more mainstream these days? Well yes, they are. If you like/prefer them, that's good. If you don't, well that's good too. It's not a competition
