Boss ME-90B Bass Multi-Effects Pedal

Create and Perform in the Moment Introducing the ME-90B, a free-flowing ME processor filled with pro performance tools for bassists. Extend your creative range with 61 effects optimized for bass. Shape your core tone with 10 bass preamps crafted with our latest AIRD technology. Connect to stage amps, house PA systems, and computers. And with the hands-on interface, expression pedal, and direct-access footswitches, you can create and perform in the moment with nothing to slow you down. For optimal performance, stay up to date with the current ME-90B system software. 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 colour for easy identification, and it's possible to set all LEDs to light in a fixed colour 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 some direct bass sound for clarity, plus a send/return loop to patch in your favourite 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 also 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-inch outputs support mono or stereo operation, with quick optimization for stage amps or line-level devices via a rear-panel switch. There's also an XLR jack with a 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. When you're ready for fresh inspiration, log onto BOSS Tone Exchange to swap Livesets with the worldwide ME-90B community. And with the optional Bluetooth Audio MIDI Dual Adaptor, you can stream music from a mobile device and wirelessly shape tones using the BTS editor app for iOS and Android.
