Rithimic Series is designed and inspired by Jeff Berlin, created by Cort. Jeff Berlin is known as one of the greatest bass players in the world and is also considered one of the finest clinicians in music.

Cort Guitars and Jeff Berlin have collaborated to release the Jeff Berlin bass since 2014. Jeff's basses have always been simple and vintage-inspired but then tweaked to his exact specifications to make them something special. The Rithimic provides that same balance between vintage, simple, and well evolved for today's playing demands.

The bass features an alder body with a beautiful exotic wood top. Outfitting the body are a pair of Bartolini Jeff Berlin custom soap bar pickups, a Babicz Full Contact Hardware bridge, one volume control, one balance control, one tone control, passive electronics, and gold hardware. The hard rock maple neck is complemented with a rosewood fingerboard and four inline headstocks featuring Hipshot Ultralight tuners. The action on the bass is low, and it is set up with DR Strings Custom DDT (Drop Down Tuning) for easy playing.

"After playing the same bass for so many years I was not sure that another builder could develop something that I would love. As soon as I played the very first Cort Rithimic bass, I was wowed. I could not believe how perfectly this bass turned out. This is an astonishing instrument that Cort has built for me."

Alder Body with Spalted Maple and Padauk Top 

Custom-designed body with the beautifully visualized Spalted maple and Padauk top make you try to play the bass. The alder body has its own unique clarity and brightness. 

Bartolini® Jeff Berlin Custom Soapbar Pickups 

The only existing Custom Soapbar pickups for neck and bridge designed by Jeff Berlin offer warm, deep tones with a piano-like low end. The pickups are a split coil design with a well-defined magnetic field aperture for maximum clarity and tonal response. 

Babicz® FCH4 Gold Bridge 

The full contact hardware technology results in an increased dynamic range, increased sustain, and pitch stability. String action and intonation adjustments remain secure, even when removing strings. 

Hipshot® Ultralite Machineheads 

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