Pyramid Strings

If you like the small size and playability of the U-Bass, but prefer for a more traditional "electric" vibe and feel, these strings may be what you're looking for.

They have a nylon/silk core, wound in silver-plated copper. They have an overall tension, sustain and tone of a more traditional electric-acoustic bass, so if you're looking for the U-Bass to fill that particular role, these are the strings to use.

IMPORTANT NOTE about stringing the Pyramid strings:

The tapered end of the string is meant to feed in to the internal hole of the tuning post WITHOUT TRIMMING. Insert it into the hole in the centre of the post, do a right-angle bend into the slot, and start turning the key. Once you initially start winding, there's some slack and it will eventually build tension after a couple winds.

   DO NOT: Cut or trim the tapered end
   DO NOT: Extend the string to where it has tension and wrap it around the post

Trimming the string, or stringing part of the wound part, can result in string damage or failure.

Kala Metal Round Wound

Looking to take the sound of your Kala U-Bass to the next level? Why not replace the strings of your 4-string U-Bass with the Kala Metal Round Wound string set. These strings have a nylon core with silver-plated windings that provide accurate intonation and a warm but powerful sound. Even though this set is designed for the Kala U-Bass, you can also use it on similar models by different brands.

Thundergut string review here

The new Silver Rumbler strings are made exclusively for Kala by Aquila; they have a little bit more tension than the classic UBASS strings. They use a special "Nylgut" compound to give them increased density and stability - as well as, they claim, the ability to resonate tone at very low frequencies. They reportedly have a clearer tone and solid low end - and are significantly different than the Kala Pahoehoe U-Bass set. This is the "OEM" string that comes stock on the Rumbler U-Bass.


The Thunder Reds sets: a unique look and a strong, consistent sound.

Until now, it was necessary to increase a string’s gauge to reach lower frequencies. But increasing the string’s diameter also increases internal dampening. That makes the string less bright, less responsive and more muffled:

the thicker the string, the duller the sound.

Our revolutionary new approach —never introduced before us— changes the specific weight of the material, increasing it progressively to leave the gauge unchanged.

Red Series strings are basically a mixture of elastic plastic mixed with copper metal powder to make the sound rich and powerful. They are designed and manufactured at our headquarters in Vicenza – Italy

Key Features:

1) A powerful sound, rich and warm, excellent sustain.

A truly innovative sound with sonority very similar to the timbre of the double bass. There is nothing comparable with these strings on the market, either wound or in alternative materials.

2) They do not rotate and do not stick:
in the past the attempt of many companies by experimenting with new materials to produce alternative strings to traditional wound strings achieved poor results due to resistance of the material to the fingers, such as for silicone, or for annoying rotation of the string that makes extremely difficult to play.
