4 string bass guitars have standard 19mm string basses that Fender created a long time ago. Most company's seem to follow with that spacing. Wen I moved to a 5 string I bought a G&L which has more narrow string spacing. I loved it because if your into jazz and your playing solos, it is easier on your hands to reach the strings. I did find slap a little harder since the strings are a little closer together, but I got used to it and over the years is was a non issue. This year I purchaed a Fender 24 fret 5 string. The string spacing is at the 19mm which means you have to stretch your fingers more when playing a solo. Ugh. In seeing Victor Wooten or Stanley Clarke their 4 strings neck are very skinny and easier to play as they have more narrow string spacing. The Carvin Brian Bromberg bass also has more narrow string spacing. But in doing some investigation it seems most company's use the standard 19mm spacing. The logic is you want the spacing the same on a 4 string or 5 string model. It makes the switch from 4 string to 5 seem more natural since the spacing is the same. I get that and it makes sense. But soloing with that spacing is more difficult. Not sure if I want to keep my bass....thinking about getting the Bromberg bass instead. However I like the sound of my bass that came with Seymour Duncan jazz pickups and active electronics. Playing below the 12 fret is not much of an issue so I am thinking maybe just keep it. People like Anthony Willington actually like the 19mm spacing on this 5 string and his hands are smaller than mine. What are your thoughts on string spacing on 5 string bass guitars?
