Ibanez BTB605 5-String Bass – Transparent Gray Flat (B-Stock)

The Ibanez BTB605 is a long-scale, neck-through 5-string bass designed for extended low-end clarity, powerful sustain, and modern tonal flexibility. Finished in sleek Transparent Gray Flat, this BTB delivers professional performance with refined aesthetics.

This is a B-Stock instrument, it has some cosmetic blemishes around the control knobs, but is fully functional and professionally inspected to meet performance standards.

35” Scale & Neck-Through Construction

Featuring an extended 35” (889mm) scale length, the BTB605 provides tighter string tension and enhanced definition on the low B string. The 5-piece Maple/Jatoba neck-through construction ensures exceptional sustain, stability, and seamless upper-fret access.

Okoume Wing Body & Rosewood Fingerboard

The Okoume wing body offers warm midrange character and balanced resonance, while the rosewood fretboard with white dot inlays adds smooth response and classic feel. 24 medium frets plus a zero fret provide consistent tonal response and comfortable playability across the entire neck.

Passive α1 Pickups & 3-Band Active EQ

Equipped with Ibanez α1 passive pickups in both neck and bridge positions, the BTB605 delivers clear articulation and focused low-end punch. The Ibanez Custom Electronics 3-band EQ with a 3-way mid frequency switch allows precise tonal shaping, making it adaptable for rock, fusion, gospel, progressive, and modern styles.

MR5 Bridge & Pro-Level Hardware

The MR5 bridge with wide 19mm string spacing provides comfortable fingerstyle and slap technique. Durable Cosmo Black hardware completes the modern, understated look.
