First, their necks have always been great, simply through careful wood selection, but they took it to a whole new level when combining that with not just one, but two carbon rods – increasing the neck strength by up to four times.

Let’s talk about some of those improvements, specifically. They include dual carbon fiber rods in the neck, a 5-bolt neck plate, JVA vintage plain enamel-wire single-coil pickups, a new preamp design with a cleaner signal path, better balance when strapped on, and optional ’60s position pickup placement (moves the bridge pickup about 1/2 inch closer to the neck).

In fact, there are multiple significant new features to the JB. This is not just a repackaging of the previous models. The JB model borrows from a rich lineage of prior Carvin models inspired by the Fender Jazz Bass, and features some recent improvements. In fact, the bass we’re reviewing here was designed by Mark Kiesel. Mark and Jeff Kiesel run the show, protect the heritage of the line, do all the designs and day-to-day business, and generally keep the fire alive. Currently, all Kiesel and Carvin guitars and basses are made in the San Diego location by a staff of around 50 people.

Kiesel Company – later becoming Carvin and expanding product lines into other areas – has returned to its roots and is now called Kiesel Guitars. The guitar-building company that started out in 1946 as the L.C. We’ve done the company line on Carvin previously, but as of February, 2015, a change has occurred.
