BTB: The "Bass Workshop" Spirit Serving Excellence

Designed in the lineage of the experimental "Bass Workshop" models, the BTB605MS embodies Ibanez's philosophy: ambitious luthiery, modern ideas, and high-end yet accessible components. The BTB double-cutaway body and neck-through design make it a flagship model in the range for bassists seeking an inspiring and reliable instrument for both stage and studio use.

For Which Bassist and Styles?

Intended for intermediate to professional bassists, the BTB605MS excels in contexts requiring definition and dynamics: metal/djent, modern rock, fusion, gospel, and contemporary music. The multiscale design provides precise attack on the low end, while the ergonomics and versatile electronics facilitate eclectic setlists.

The Sound

The T1 humbuckers deliver tight lows, punchy mids, and clear highs. The separately mounted coils allow individual height adjustment for each coil to fine-tune string-by-string balance, while providing a comfortable thumb rest. The 3-band preamp sculpts the spectrum with a 3-position mid frequency selector and a bypass that switches to passive mode (where the treble control becomes a master tone). The combination of okoumé wings, panga panga fingerboard, and maple/walnut neck-through construction offers projection, sustain, and tight response in the low-mids. The 37"-35" scale length stabilizes the low B for precise sound even in dropped tunings.

Recommended Compatible Accessories

To get the most out of the BTB605MS, choose a 5-string "super long scale"/multiscale string set compatible with 37", a comfortable standard bass strap, and a quality right-angle to straight jack cable to secure the output jack on the body. The hard case is included, ideal for transport and protection.
