Guitar Neck Diagram
a: Width of the neck at the nut
b: Width of the neck at the first fret
c： Thickness of the neck at the first fret
d: Thickness of the neck at the twelfth fret
Radius: Radius of the fingerboard
With the bass held in the playing position, there are three small knobs closest to the lower edge of the body. Directionally, from the lower bout towards the neck knobs are treble boost/cut, mid boost/cut, and bass boost/cut. There are two larger knobs above these, closer to the bridge. The knob closest to the neck controls volume, and the knob next to it is the pickup balancer control. There is a 3-way power tap switch next to the balancer knob. When the switch is in neck position, the humbuckers are tapped. When the switch is in center position, the humbuckers are in series. when the switch is in bridge position, the humbuckers are in power tap mode, which is tapped with additional low end added.
The bass boost/cut frequency curve has a peak at 20 Hz, the variable width becomes smaller toward the high range, and the variable width becomes zero at about 1000 Hz. The variable range becomes slightly larger in the high range than around 1000 Hz, but it becomes zero again near 5000 Hz. The variable range of the peak frequency is approximately ±15 dB. The treble boost/cut frequency curve draws a mountain-shaped curve with a peak at around 10,000 Hz and zero variable range around 100 Hz. The variable range of the peak frequency is approximately ±15 dB. The mid-boost/cut frequency curve creates a bell-shaped curve with a peak around 450 Hz, and the variable width becomes zero near 20 Hz and around 10,000 Hz. The variable range of the peak frequency is approximately ±15 dB.
The B120's extra-wide string slots can accommodate even the heaviest of gauges. The walls and channels of the new bridge plate effectively ”trap” the saddles, ensuring perfect directional uniformity.
Developed by Ibanez, the exposed pole pieces of the PowerSpan Dual Coil pickups produce a stronger signal and increase the response of the higher frequencies without sacrificing low end. The result is a tone rich in harmonic detail and dynamic expression.
The 3-band EQ works in conjunction with a coil tap switch for maximum control over a wide variety of professional bass tones. Tap Mode (single coil) creates a punchy, dynamic sound with superior articulation. Series Mode (humbucking) delivers a full, warm tone, and Power Tap Mode provides the best of both worlds-combining the clarity of the single coil with the fat bottom end of the humbucker.
Jatoba has a reddish brown color which produces a rich mid range with a crisp high end.
