The BTB33 is a five string BTB series solid body electric bass model introduced by Ibanez for 2015. It is made in Indonesia as part of the Ibanez Bass Workshop line.
The BTB33 is the first shorter scale addition to the Ibanez Bass Workshop range of instruments that have been designed to bring concept-style basses to the masses. Due to its shorter scale length, the BTB33 is tuned from E-C, a feature that is unique within the Ibanez bass guitar range.
The BTB33 features neck through body construction with ash top and mahogany back on ash wings attached to a maple and bubinga neck with a 24-fret rosewood fingerboard with abalone dot position markers. The body has a double cutaway design with very distinctive, narrow, curving horns. Components include a pair of Bartolini BH1 soapbar-style pickups with an Ibanez custom preamp with a three-band EQ, stainless steel frets including a zero fret, Mono-rail bridges with 19mm string spacing, a locking Neutrik stereo output jack, a plastic nut and Ibanez tuning machines.
