The JBM line consists of three models (as of 2018). All three models are based on the arched-top super-Strat RGA body. The three models are visually similar with a reversed headstock (they are the first production RGA models with this feature), black finish with black hardware except for the machine heads, which are gold. They all feature DiMarzio Titan pickups, a Floyd Rose-style tremolo and a simple control setup eschewing a tone control.
The Prestige-level JBM100 was introduced in mid-2014. It has a mahogany body with a maple top and a black finish with dual DiMarzio Titan humbucking pickups and a Lo-Pro Edge double locking tremolo bridge. Controls consist only of a master volume knob and a 5-way pickup selector level. Another high-end feature of this model is the Sperzel Trim-Lok tuning machines.
The JBM20 was introduced in 2016. It is a more affordable mass-market version of the JBM100. Both models have the same body and finish, the same pickups and the same controls. Differences between the JBM20 and JBM100 include a 3-piece maple neck (instead of the JBM100's 3-piece maple and bubinga), a rosewood (rather than ebony) fingerboard, an Edge Zero II (rather than Lo-Pro Edge) tremolo and Gotoh (rather than Sperzel) locking tuners.
The JBM27 was released in 2016 alongside the JBM20. It is a seven-string model with very simlar features and components to the JBM20.
