You Now Have (String) Options



Kala uBasses (from left) The Rumbler, Bubinga and Exotic Mahogany are now available with string options.


As pointed out by Bass Player magazine, Kala is now offering its uBass models with different string options.

In an article on their online site, they point out that Kala is now offering Road Toad Polyurethane Pahoehoe, Aquila Silver Rumbler and Kala Roundwound strings on some models.

Not exactly new, the uBass models have been available for a while (all except the Bubinga, which is fairly new) and you could get the strings separately and restring your uBass if you were so inclined. Still, it’s nice to know Kala is offering options if you are not a fan of the original Pahoehoe strings.

You can now get The Rumbler U-Bass with Aquila Silver Rumbler strings, which are designed “with increased density and stability for a clear, resonate low end.”

You can buy the The Bubinga U-Bass strung with Road Toad Polyurethane Pahoehoe strings, which gives “it a deep, punchy low end.”

Or you can buy The Exotic Mahogany U-Bass with Kala Round Wound strings that adds “treble while retaining the immense low end.” Pahoehoe also are available on the Exotic Mahogany if you prefer.

Kala Affected by Rosewood Restrictions



East Indian Rosewood is one of the Rosewood species restricted for export.


Like all companies selling instruments and products containing Rosewood, Kala is affected by the new regulations restricting Rosewood species sales across borders.

The company has placed this disclaimer on its web site:

Please bear with us—due to new International Export Regulations regarding all species of Rosewood there will be an undetermined postponement of orders containing Kala Elites, California U-Basses, and USA Banjo Ukulele shipping outside the United States. We hope to have this resolved as soon as possible.

The Convention of International Trade of Endangered Species of Flora and Fauna (CITES) held a conference from September 24 to October 4 this year in Johannesburg, South Africa, where it was decided that all species of rosewood under the genus Dalbergia and three bubinga species (Guibourtia demeusei, Guibourtia pellegriniana, and Guibourtia tessmannii) will be protected and its export restricted, according to

The restrictions went into affect January 2.

Kosso – sometimes called African rosewood (Pterocarpus erinaceus) – will also be protected, they note.

While Brazilian Rosewood is was already under CITES protection, now all the nearly 300 other species of rosewood are under similar regulation. This includes East Indian rosewood and Honduran rosewood – as well as woods like cocobolo (Dalbergia retusa) and African blackwood (Dalbergia melanoxylon) – that are widely used in the manufacturing of stringed instruments, marimbas and some woodwinds.

Rosewood is the world’s most trafficked wild product, according to the UN Office of Drugs and Crime, accounting for a third of all seizures by value, more than elephant ivory, pangolins, rhino horn, lions and tigers put together.

So, if you’re an overseas customer of Kala’s, prepare for delays if you buy an instrument form them. Sales shipped within the United States are not affected. If you already own an instrument with rosewood and have it in your possession, there’s no need to worry. You can also travel with previously purchased instruments with no restrictions.

If you thought the new Kala Rumbler uBass couldn’t rock – or that uBasses in general don’t rock – Mike Upton of the Kala Brand Music Co. is here to prove you wrong.

In this video, Mike shows off the new Rumbler uBass. And he’s not just playing it through a bass amp – he’s playing it through a freaking Ampeg SVT Blue Line amp with an 810 cabinet!

Let me say that again. An Ampeg SVT!

You can’t get any more rock and roll than that.
