Clef Gut Jazz Bass Strings are a high quality European-made gut double bass string with a classic tone and stability that is sure to last. The E and A strings are silver wound and the D and G strings are plain gut.  

These double bass strings are handmade by European craftsman using only mutton serosa (sheep intestine). Mutton gives a lower tension, softer feel, and warm rich tones within the string. It is far too delicate to process by machine, and even the twisting of the strands into a string is done by hand—it’s the only way to properly judge the tension of the string. Clef Gut Jazz Bass Double Bass Strings are available in full sets only.

Gary’s Thoughts: Our customers have been loving these Clef Gut Jazz Bass Strings for years. The lowest strings have a nicely distinct but warm tone, and the silver windings help to achieve the mass necessary for the lower notes. This means that your bass will have more fundamental on the low end without the larger diameter.

Jack’s Thoughts: A great set of strings; good for any rockabilly, blues, jazz, or other old style sound. The lower tension on this set makes a nice “playable” choice for those with a more aggressive style.

As gut strings are a natural product, time of usefulness is an unknown.  Weather, pH of user, care, musical style, etc. can all diminish longevity. Our Jack Hanlon’s are quite old, but he’s religious about oiling them.
