EarthQuaker Devices Scrolls Bass Odyssey Preamp & Drive (Designed with 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.

• 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!
