Boss ME-90B Bass Multi-Effect Pedal.
Filled with pro performance tools for modern bassists, the ME-90B from BOSS offers 61 studio-quality FX from the BOSS bass FX library as well as 10 bass preamps crafted with the latest AIRD technology. With a hands-on interface, eight multifunctional footswitches, and an expression pedal, you can create and perform without restrictions.
Along with the bass preamps, you can load up to three speaker IRs for a full amp experience when outputting direct signals. The ME-90B sports superior sound quality with its 24-bit / 48 kHz sampling, 32-bit floating point DSP, and 32-bit D/A audio conversion. Tweak your tone in real time with Manual mode or save color-coded configurations for your specific set list with Memory mode. Lightweight and durable, the ME-90B is designed to be an ideal companion for any home creator, studio session player, or gigging musician. The ME-90B can run off of battery power or an optional AC adapter and includes four AA batteries to get you started.
Effortless Creative Control
The ME-90B delivers everything a performing bassist needs, accessed via the classic BOSS ME interface for fast stompbox-style operation. Each effect category features independent parameter knobs, allowing you to tweak tones instantly.
Manual mode provides on/off footswitch control of each category, while Memory mode lets you call up 36 custom multi-effect setups. Every footswitch has a different LED color for easy identification, and it's possible to set all LEDs to light in a fixed color for each mode if desired.
Premium BOSS Effects
The ME-90B comes stocked with premium selections from the BOSS bass effects library, organized into six logical sections that can be used simultaneously. Apply essential tone shapers like compressors, pitch effects, and filters. Explore more aggressive textures with drive and synth effects.
Expand your sound with modulation, delays, and reverbs. And dive into a variety of dedicated effects for the onboard expression pedal. There's also a Blend knob to mix in your dry bass sound for clarity, plus a send/return loop to patch in your favorite stompbox effects.
Solid Bass Tone
A strong fundamental sound is the foundation of any great bass rig. The ME-90B's Preamp/EQ section features ten inspiring preamp types backed by advanced AIRD technology, complete with gain and EQ controls for rapid sound adjustment.
Express your individual voice with BOSS originals like Natural and Drive Bass. Or call up authentic models of classic bass amplifiers from vintage to modern. There's an Acoustic type optimized for acoustic-electric and upright bass pickups, plus an EQ-only option for clean DI tones.
Perform, Practice, and Record
With its versatile connectivity and compact, battery-powered design, the ME-90B is ready for every playing scenario. The 1/4" outputs support mono or stereo operation, with quick optimization for stage amps or line-level devices via a rear-panel switch.
There's an XLR jack with ground lift for sending a balanced DI signal to a house PA. The ME-90B's preamps and effects provide studio-quality sound for direct USB recording in music production software. And with the headphones jack, you can quietly hone your chops while jamming with backing tracks from a computer over USB.
Edit, Customize, and Expand
BOSS Tone Studio for Windows and macOS extends your creative range with the ability to edit tones and change out some preamp and effect types with alternate selections. You can also organize memories for different gigs and supplement the onboard speaker IRs with three from your own library.
