The Ibanez BTB Standard 7-String Electric Bass incorporates all the staples the Ibanez brand is famous for, such as fast necks, floating terms, and high-octane distortion in a package that is available and accessible to most players.9pc Maple/Walnut Neck with Graphite Reinforcement RodsThe 9pc Maple/Walnut neck provides tonal clarity and superior attack. The Graphite reinforcement rods provide massive sustain and excellent stability.Rosewood FretboardRosewood provides a well-balanced solid tone with a focused mid-range.Ibanez Custom Electronics 3-Band EQ with Mid Frequency SwitchIbanez Custom Electronics 3-band EQ is the latest refinement on the concept of simple, straightforward, no-nonsense EQ control. The Boost and Cut for the Mid Control are each centered on slightly different frequencies, an innovation that delivers a preset range of the most favorable bass tones.Bartolini BH2 PickupsThe Bartolini BH2 pickups provide a tight bottom-end, punchy mid-range, and smooth response. The dual-coil style configuration maximizes articulation and a long blade pole piece widens the magnetic field, providing a balanced string-to-string pickup response.MR5 BridgeThe Mono-Rail V is the ultimate bridge for bass string isolation. Each bridge is independently and securely locked down to the body for maximum vibration transfer without interference.ControlWith 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 mid-frequency switch next to the balancer knob. When the switch is in the neck position, the mid-boost peak is at 250Hz. When the switch is in the center position, the mid-boost peak is at 450Hz. When the switch is in the bridge position, the mid-boost peak is at 700Hz.Frequency ResponseThe 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 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 a zero variable range of 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 that peaks at a specific frequency, and the variable range becomes zero near 20 Hz and around 10,000 Hz. The frequency peak can be switched to 700, 450, and 250 Hz. The variable range of the peak frequency is approximately ±15 dB.
