Review: The best. - The very best bass strings you can buy. Excellent tone, perfect intonation, and they last for years. Low tension at pitch makes them easy to play. Thomastik-Infeld has been making strings for the most demanding musicians - orchestral string players - for over 100 years and it shows. I had a new bass coming, and I ordered these to make sure the new instrument would sound as good as it can.
Review: Tomastik Jazz Bass Flatwound Strings - I needed to get some flat wound strings for my MusicMan Big Al bass. I had just sold the Precision which had Fender flat wound strings, the Big Al still had the Ernie Ball round wound strings that it came with, ok strings but not for me. I checked around on the web and asked friends to find out what was recommended, I thought there might be something better than the Fender flats. Thomastik came up more than anything else so I got some. The Big Al has passive and active circuit options that allows you to dial in any kind of sound. I use a David Eden World Traveler combo that will reproduce anything the instrument delivers with clean power and control. I actually tried the new strings out with a couple of the Ernie Ball round wounds still left on to compare, before putting all of them on. The Thomastik flat wound strings have a full, singing tone that I hear in my head and want my bass to have. With the full tone one can achieve the bright tones that round wounds produce, the deep bassy tones for recording and stage and everything in between with no gaps. There is no change of tone when going from string to string and likewise with the sustain. Each string acts and plays like all the others. Since the Big Al also gets a wide variety of sounds, these strings are an excellent match. The smoothness of the strings are the best part. If you are playing for hours at a time, the Tomastiks will not fatigue your fingers or tear up the frets. Also, if you want to set the action low, these strings will not mind. If you just cannot get the sound you want from your strings (and you have a decent quality of an instrument) I would say give these strings a try. If you like round wound sound and your bass has an active circuit, you may be able to get by with these flats, otherwise Thomastik does produce round wound sets. I expect to get years of use from a set so the higher cost will balance out over the years. The only caveat from me is the G string broke off several times when making a right angle turn in the machine head, they are kid of soft. I ended up just using a figure S around the slot to get it started. Make sure you start off with enough length and to wind it properly down from the nut.

### ⭐⭐⭐⭐⭐ The “Rolls Royce” of Bass Strings — Carol Kaye Was Right
*by J***. on November 23, 2025*

After trying several flatwound sets over the years, the Thomastik-Infeld Jazz Flats (JF344) stand out as something very special. I still believe LaBellas are unbeatable for that classic Motown thump, but for almost everything else I’d choose these. They have a "singing" clarity that feels almost effortless—likely due to the lower tension which I normally don't like. The nickel wrap gives them a soft, silky texture that’s unlike any other flatwound I’ve tried. They’re incredibly comfortable but not flimsy. Carol Kaye called these the “Rolls Royce of bass strings,” and after playing them, I agree. Every time I pick up my Precision with JF344s, I’m inspired. Truly amazing strings.
