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. These strings are similar to Clef Gut Upright Bass Strings, but the A and E strings are silver wound while the D and G remain a plain unwound 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 Double Bass Strings are available in full sets only. Sorry, no individual strings.

Gut String Oil is highly recommended to extend the life of any gut string set. Purchasing the set and oil together? Follow this link to the combo deal and receive 25% off your gut string oil.

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. We’ve heard of breaking after 30-60 days and we’ve heard of them lasting years. Our Jack Hanlon’s are quite old, but he’s religious about oiling them. PLEASE NOTE: The winding portion of the string on a wound gut E  & A Strings CANNOT be wound onto the peg or they WILL break.

  1. Michael Collins (verified owner)

    I just installed these strings yesterday and although they are still stretching out they seem to sound wonderful. I cannot wait until they break in. If I could have one request it would be for the strings to be a little longer. They barely reach the two back tuning machines. Especially the d string it is very short, and it’s a good thing they stretch! I hope it holds! Other than that I received them safely and in good condition. Thanks…
