Panga Panga Fretboard

The Panga Panga fretboard provides a tight low and midrange response, paired with sharp, articulate highs. Its striking grain adds a boutique aesthetic to the BTB605MS.

Medium Stainless Steel Frets

Stainless steel frets are designed for long-lasting durability, while their medium size provides effortless playability and consistent articulation.

Okoume Wing Body

The Okoume wing body delivers a bright, punchy tone with excellent resonance, making it ideal for bassists seeking both power and nuance in their sound.

T1 Pickups

The T1 humbucker pickups feature individually mounted coils for unparalleled tonal flexibility. They produce a tight bass response, punchy mids, and clear highs, suitable for any genre. Adjustable coil height and ergonomic design enhance comfort and tone precision, making this an incredibly player-friendly feature.

Ibanez Custom Electronics 3-Band EQ

The 3-band EQ is a refined tool for dialing in your sound, offering a broad tonal palette with precision control. The boost and cut for mids are centered on different frequencies for even greater tonal flexibility.

EQ Bypass Switch with Passive Tone Control

Switch seamlessly between active and passive modes with the EQ bypass switch. When bypassed, the treble control acts as a global tone control for the passive circuit, adding versatility to your sonic arsenal.

3-Way Mid Frequency Switch

The 3-way switch lets you choose from three different mid-frequency centers, giving you a wide variety of tonal options to suit any musical context.

MR5S Bridge

The MR5S bridge allows for precise adjustments to string spacing by +/-1.5mm, catering to your exact playing preferences.
