The BTB686SC is a six string BTB series solid body electric bass model introduced by Ibanez for 2014. It was made in Indonesia as part of the Ibanez Bass Workshop line.
The BTB686SC "Terra Firma" features neck through body construction with a rosewood top 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 single cutaway design with a very prominent upper bout and a narrow, curving lower horn which meets the neck from the 12th to the 24th fret. This design is said to maximize stability and provide increased sustain.
