Ibanez SR505 EBAB - Black Aurora’s Burst

The Ibanez SR505EBAB SR Series Black Aurora Burst 5 String RH Bass Guitar has a Accu-cast B500 bridge and 24 frets.

Rosewood fretboard
Rosewood provides a well-balanced solid tone with a focused mid range.

Accu-cast B500 bridge
The Accu-cast B500 bridge has adjustable saddles for variable string spacing by +/- 1.5mm, answering every bassist's specific string spacing needs.

Bartolini® BH2 pickups
The 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 balanced string-to-string pickup response.

Ibanez Custom Electronics 3-band EQ w/EQ bypass switch & Mid frequency switch
Ibanez Custom Electronics 3-band EQ is our 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.
Precision tonal control, including a switch to choose passive-only operation. When the EQ bypasses activated, the treble tone control knob becomes the global tone control for the passive circuit.

Controls
With the bass held in the playing position, there are three small knobs located towards the lower edge of the body. Directionally, from the lower bout towards the neck these knobs control treble boost/cut, mid boost/cut, and bass boost/cut knob. Above these are two larger knobs closer to the bridge. Of these, the knob closest to the end of the body is the pickup balance, and the knob located towards the neck is the volume knob. There are two switches on this bass. The switch closest to the lower edge of the body is a 3-way mid frequency switch. When the switch is in neck position, mid boost peak is at 250Hz. When the switch is in center position, mid boost peak is at 450Hz. When the switch is in bridge position, mid boost peak is at 800Hz. The other switch closer to the middle of the bass is the EQ bypass switch. When the switch is in neck position, the EQ is off. When the switch is in bridge position, EQ is on. When EQ is off, the treble knob works as a passive tone control knob.

Frequency Response
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 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 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.
