Thunderguts and the Solidbody

Mike Upton Trying Out a Set of Aquila Thundergut Strings on a Solidbody uBass.

If you were wondering how Aquila Thundergut strings sound on a Solidbody uBass, wonder no more.

Kala uploaded a video of Mike Upton testing out a set of Thunderguts on the Solidbody.

The Thunderguts for the Solidbody are slightly different from the T-guts for the Acoustics, in that they have terminations on the ends of the strings so they won’t slip out from the holes in the body.

The T-gut strings aren’t listed on the Kala or Kala Gear web sites yet.

UPDATE 5/31: According to Mark Milazzo of Kala, the Thundergut terminations are being fabricated now and the strings should be available for purchase soon. “We are doing the terminations for Thunderguts for Solid Bodies in our California custom shop. They will be available at in a couple of weeks. If you want to know when they become available drop me a note at Thanks for all the support and interest in the Kala UBass!”

Justin Oscar Cary, a bassist based in Nashville, runs a nice blog featuring gear reviews and other ramblings about the bass and being a professional bassist. It’s worth a look if you’re into playing bass.

He recently posted a review of the Aquila Thundergut strings for the uBass. He even posted sound clips of the Thunderguts and of the Thunderguts vs. the stock Pahoehoe string. It’s well worth a read.

According to Justin’s review of the Thunderguts:

The sound is very similar to the Pahoehoe strings, however the Thundergut has far more treble detail and more acoustic volume.  The volume from the instruments pickup is also a touch louder.

He concludes that the Thunderguts not only give you a bit more volume, but they are

much more stable and stay in tune better than the Pahoehoe strings.

Tuning stability is probably the greatest benefit of the Aquila string.  My set of Thunderguts took only minutes to install and reached tuning stability in only 2 days!  Tuning stability has remained at least 50% better than the stock strings.

He even shows you how to install the Thunderguts on a uBass (hint: don’t lose those red grommets on the ends of the Pahoehoes).

You can pick up a set of Thunderguts at Ukulele World for $22.95 plus shipping. In the U.K. try Bass Direct. They have Thunderguts for £25 plus £2 shipping.
