The BTB25th6 is a six string BTB series solid body electric bass model introduced by Ibanez for 2024. It was produced in Indonesia as part of the Standard line and was released as a limited model to commemorate the twenty-fifth anniversary of the BTB series.

The BTB25th6 features neck through body construction with okume wings attached to a maple and walnut neck with graphite reinforcement rods and a 24-fret rosewood fingerboard with acrylic block inlays. The body has a double cutaway design with very distinctive, narrow, curving horns. Components include a pair of Nordstrand Big Single passive pickups channeled through a Vari-mid III 3-band EQ preamp with variable mid-frequency crossover, individually mounted Mono-rail Vs bridges with adjustable 17mm string spacing, a locking Neutrik stereo output jack, a plastic nut, and Ibanez die-cast tuning machines.

The BTB25th5 is a five string version.

The BTB25th6 was discontinued after 2024 in all markets except Japan; it was discontinued completely by February 2025.
