I play 5ers pretty much exclusively as, for me and the music I play, it is an absolute necessity. I listen to a lot of Neo-Soul/R&B etc which frequently utilises notes below an E, plus I play covers with friends that often need transposing down from the original key to be comfortable for whoever’s singing. While the guitarist does mental maths for however long it takes to transpose the chord structure, I can simply shift the whole line down by however many frets and quickly get back to the enjoyable part of actually playing music.
With this in mind, a 5 string isn’t just a “want” for me. It’s a necessary tool.
