Scrolls™
Bass Odyssey
A collaboration between EarthQuaker Devices and Kentaro Nakao.
Scrolls Bass Odyssey is a sonic pilgrimage through the entire universe of electric bass tone. From Motown to Metal and everywhere between and beyond. With a tube amp-like drive channel, an active EQ channel with three push-button switches for one-click tone sculpting, buffered parallel out, onboard effects loop, and balanced XLR out featuring just a splash of analog filtering to emulate a speaker cabinet, Scrolls is a powerful, modern tool that’s compact and versatile enough to be the only thing you need to play a session or show other than a bass.
Controls:
EQ Controls:
- Level: Output volume control when the EQ controls are active. Set the knob at noon for unity, turn clockwise to boost the output signal, turn counterclockwise to cut the output signal.
- Vari: Boosts or cuts the Variable Frequency control. Position this control at noon for unity (marked with a center detent in the potentiometer.) Turn clockwise from noon to boost the Vari-Freq, or counterclockwise to cut.
- Vari-Freq: Variable frequency control for fine-tuning your tone. Adjustable from approximately 20 Hz to 10 kHz.
- Treble: The center position is flat and marked with a center detent in the potentiometer. All settings above this point boost the treble and all settings below cut treble.
- Bass: The center position is flat and marked with a center detent in the potentiometer. All settings above this point boost the bass and all settings below cut bass.
- Middle: The center position is flat and marked with a center detent in the potentiometer. All settings above this point boost the middle and all settings below cut middle.
- Deep: 80 Hz Boost.
- Process: Low-mid scoop for a more modern sound.
- Bright: 5 kHz Boost
- EQ Footswitch: Activates the EQ channel
Drive Controls:
- Level: Output volume control for the Drive channel.
- Blend: Blends between your clean signal with the Drive signal. Turn the knob fully clockwise for maximum crunchiness.
- Drive: Controls the intensity of the overdrive.
- Bandwidth: Determines where the clipping is most active. Turn the control counterclockwise to activate low-end clipping for a warmer, softer, rounded, and overall more subdued tone. Turn the control clockwise and activate High-end clipping for a present, focused crunch with a tighter low-end.
- Tone: Low pass filter enabling you to shape the frequency of the Drive channel. Turn counterclockwise to reduce highs.
- Drive Footswitch: Activates the Drive channel
Outputs:
- Parallel Out: Buffered output carrying your clean signal that is always active. This allows you to route your clean signal to external destinations (amp, DI, separate pedal chain, tuner, etc.)
- Direct Out: Balanced XLR out with a subtle amount of analog filtering added to the signal path to simulate the tonal characteristics of a bass speaker cabinet.
- Ground Lift: Press for ground lift on the XLR output.
- Effects Loop: Situated between the Drive and EQ stages. Hard-wired into the signal path and remains active at all times.
Specifications:
- Dimensions : 4.75 x 4.50 x 2.25 in. (121 × 114 × 57 mm) with knobs
- Current Draw : 70 mA
- EQ Input Impedance : 10 MΩ
- EQ Output Impedance : <1 kΩ
- Drive Input Impedance : 500 kΩ
- Drive Output Impedance : 100 Ω
- Parallel Input Impedance : 10 MΩ
- Parallel Output Impedance : 100 Ω
- Direct Output Impedance : 100 Ω
- Switching : Scrolls uses relay-based true bypass switching. Since the switching is relay-based, it requires power to pass a signal. The EQ side uses standard on/off switching, the Drive side uses Flexi-Switch® Technology.
- Power : This device takes a standard 9-volt DC power supply with a 2.1 mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
