Oberheim OB-X8 (2022–)

Name: Oberheim OB-X8
Brand: Oberheim

An 8-voice analog polyphonic synthesizer that brings back the classic Oberheim sound, with modern build and two VCOs per voice.

Overview

The Oberheim OB-X8 is an analog polyphonic synthesizer built from 2022 to the present. It is the first Oberheim synth in more than 40 years. Oberheim makes it in two form factors: a 61-key keyboard and a desktop module. Each voice has two discrete SEM/OB-X-lineage VCOs, recreated at the component level to match the original OB-series synths. There are dual LFOs, amp and filter envelopes, and a multimode filter section that combines SEM and CEM3320 designs. Firmware added a new 4-pole filter mode.

Design

The OB-X8 is pure analog, with two discrete SEM/OB-X-lineage VCOs per voice. The design aims to replicate the complex component interactions of the original OB-series synths. The filter section takes multimode features from both SEM and CEM3320 circuits, and a new 4-pole mode came in with firmware. The unit has a black finish and wood side panels, in both 61-key and desktop configurations.

Context

The OB-X8 was introduced in 2022 at Superbooth. It continues the OB line that began in 1979. Tom Oberheim and Dave Smith gave input on its development. It was the first new Oberheim synthesizer in over four decades, released under Music Tribe’s stewardship.

Market

Current market prices run from $3,100 to $3,999.99. The desktop module has an MSRP of $3,499.99. Used listings start as low as $2,462 for the desktop version and $3,200 for the 61-key model. The synth is marketed as a high-end analog revival for collectors and performers who want authentic vintage Oberheim tones.
