GB-Modern 4

A great bass has just the right blend of timeless design and modernized features. The GB Modern bass is developed for the J-Bass enthusiasts with a surprisingly lightweight design for greater comfort and enhanced playability while reducing fatigue. Also featured are top tier visual and spec enhancements such as roasted maple neck and fretboard, Hipshot® Ultralite Tuners and Babicz® FCH4 Bridge to reduce the weight even further, and an ultimate tone combination of Nordstrand® Big Single Pickup Set, paired with MarkBass® MB Instrument preamp system.

Modern 4 Lightweight Body Design

Oftentimes the weight of the instrument affects the playing experience, and on a larger instrument like a bass guitar more fatigue is caused by heavier weight. While many manufacturers seek solutions by carving out large sections of body wood to reduce weight, the GB Modern’s body is cleverly designed to be just as light without physically tempering the body. The maple body core is paired with light-weight paulownia wings, then gets covered with gorgeous poplar burl on the top side and white ash on the back, resulting in a combination of great tonewoods that is excellent both sonically and aesthetically.

Nordstrand® Big Single Pickup Set

Often considered the tonal giants of the Nordstrand® pickup lineup, the Big Single is a single coil pickup packed into a soapbar cover that uses a large magnet load for that bludgeoning bawl of extreme sonic salubrity. The Big Single's wind is able to take up the entire space of its bobbin, resulting in a super packed coil that works as the distributor of the monster tone these pickups have come to be known for.

MarkBass® MB Instrument Pre Preamp

Known for their world-class amplifiers, MarkBass® created the MB INSTRUMENT PRE by concentrating their entire knowhow into making an ultra-compact circuit and choosing the right frequencies for the best sound reproduction. Its tone control circuits were designed not only to enhance these frequencies but to give a unique and rich response when you boost/cut them, whilst always offering a very clean and focused bass tone without losing tone details. The circuits were also developed to offer subtle differences of volume when switching between the passive and active modes. It offers a wide range of wiring/application options, and works at 9V with very low power consumption for an exceptionally long battery life.

Babicz® FCH Bridge

The lightweight FCH (Full Contact Hardware) bridge by Babicz® results in increased dynamic range, improved sustain, and pitch stability. Its double saddle housing lock feature assures the string action and intonation adjustments remain secure, even when removing strings.

Roasted Maple Neck and Fretboard

By treating the Maple in an oxygen-free oven at a high temperature, the wood stabilizes and develops a golden-brownish look for enhanced stability as well as a more vintage type of look and a big bolder tone.

Hipshot® Ultralite Tuners

Hipshot® Ultralite tuners (classic 20:1 tuning ratio) are made of cast zinc with aluminum strings posts and mounting nuts, resulting in 30% weight reduction over other regular tuners and results in improved balance and tuning accuracy.

Spoke Nut Hotrod Truss Rod

The spoke nut Hotrod truss rod ensures smooth and precise setting of the neck bow. Often overlooked by many guitarists, the neck bow (or relief) is very critical for the best possible playability. This spoke nut truss rod adjustment feature allows the player to dial in the exact amount of neck bow depending on the player’s technique and playing style.

Luminlay Side Dots

The Luminlay side dot position marks make it easy for players to see the fretboard position markers when performing on dark stages.

Exclusive Deluxe Soft-Side Case

The new Cort Deluxe Soft- Side Case is not only stylish and sleek, but combines the best attributes of a hard case with the flexibility of a padded gig-bag for superb protection for the instrument as well as excellent portability.

Lightweight Body, No Compromises

Instrument weight plays a big role in comfort—especially with larger bodies like bass guitars, where extra weight can lead to quicker fatigue. Instead of removing chunks of wood to shave off pounds, the GB Modern takes a smarter approach. It features a maple core with ultra-light paulownia wings, topped with stunning poplar burl and finished with white ash on the back. The result? A lightweight design that feels great, sounds full, and looks striking—without sacrificing tone or durability.

MarkBass® MB Instrument Preamp

Built by the minds behind MarkBass®'s legendary amplifiers, the MB Instrument Pre is a compact, precision-engineered preamp designed to deliver premium tone shaping. Its custom EQ circuit focuses on the most musical frequency ranges, offering smooth, responsive control whether you're boosting or cutting—always maintaining clarity and preserving tonal nuance.

Exclusive Cort Deluxe Soft-Side Case

The Cort Deluxe Soft-Side Case blends the sturdy protection of a hard case with the lightweight flexibility of a padded gig bag. Designed for both style and function, it keeps your instrument safe during transport while offering excellent portability and a sleek, modern look.
