The key to sustain is integrity

It's difficult to imagine increasing the amount of sustain the Ibanez BTB has to offer, but with the added mass and stability afforded by this unique single cutaway reworking, the BTB Terra Firma gives you just that. Capitalizing on the shortened distance from the body to headstock, string vibration is optimized beyond anything Ibanez has ever achieved before.

Upper Horn

This extended Upper Horn creates constant contact with the Maple/Bubinga neck from the 12th to the 24th fret, providing maximum stability and increased sustain.

Contoured Neck Scoop

The back of the neck is sculpted for comfort and easy access to the very highest notes on the C string. The smooth, graceful contour allows the palm of the left hand to move quickly and easily as it transitions up the neck, into the underside of the bass's Ash body.

5pc BTB-6 Maple/Bubinga 35"" Scale Thru-Neck

The Maple/Bubinga combination creates one of the strongest Thru-Necks available. The density of the Bubinga, combined with the strength of the Maple, increases stability and sustain through the entire body of the bass. The 35"" scale provides a bit more tension for the low B and improves definition in the lower range.

Mono-Rail II bridge

The Mono-Rail bridge delivers the ultimate in string-to-string isolation, allowing each string to vibrate optimally without being affected by the others. The Terra Firma's string spacing is 17mm, offering more freedom on the fretboard and easy access for finger picking and slapping.

Bartolini® BH1-6 Pickups

Balancing clarity with warmth is the hallmark of the Bartolini® BH1-6 pickup. Coils with lower resonant frequency provide tighter bottom end and a fuller midrange. The dual-coil style configuration maximizes articulation and a long blade pole piece widens the magnetic field, providing balanced string-to-string pickup response.

EBQ-IIIS 3-Band EQ With Mid Frequency Switch

The active 3-band EQ features fully independent bass, treble and mid controls with a wide boost/cut range. The preamp system is equipped with a mid-frequency select switch, enabling you to instantly select 250Hz or 600Hz, the heart of the mid zone, for a more dynamic and ideal tone.
