BOSS Announces ME-90B Bass Multiple Effects

Floorboard processor with performance tools for bassists   19-Apr-24

BOSS has announced the ME-90B Bass Multiple Effects, which they describe as a free-flowing processor filled with pro performance tools for bassists.

A spokesperson told us, "The BOSS ME series has been a favorite of gigging musicians for over three decades, combining multi-effects power with hands-on control for building tones in seconds. The ME-90B features 61 unique effects optimized for bass and 10 bass preamps crafted with advanced AIRD technology, housed in a rugged, all-in-one package that's ready to travel anywhere."

Here's more details direct from BOSS...

The ME-90B delivers everything a performing bassist needs, accessed via the classic BOSS ME interface for fast stompbox-style operation. There are eight footswitches and an expression pedal with an integrated toe switch, and the onboard effects are organized into logical categories with independent parameter knobs. Manual mode enables on/off footswitch control of each category, while Memory mode provides 36 custom multi-effect setups to choose from. 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.

The vast effects selection in the ME-90B includes essential tone shapers like compressors, pitch effects, and filters, powerful drive and synth effects, and a wide variety of modulation types, delays, and reverbs. There are also many dedicated effects for expression pedal control. A Blend knob allows the player to mix in some direct bass sound for clarity, and a send/return loop is available to patch in favorite stompbox effects.

The ME-90B's Preamp/EQ section features ten AIRD preamp types, complete with gain and EQ knobs for rapid sound adjustment. Included are BOSS originals like Natural and Drive Bass, along with 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.

With its versatile connectivity and compact, battery-powered design, the ME-90B can take on 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 headphone jack, players can quietly hone their chops while jamming with backing tracks from a computer over USB.

BOSS Tone Studio for Windows and macOS allows users to edit tones and change out some amp and effect types with alternate selections. It's also possible to organize memories for different gigs and supplement the onboard speaker IRs with three user-supplied selections. The BOSS Tone Exchange website provides a growing range of professional sound collections and the ability to share Livesets with the worldwide ME-90B community. Using the optional Bluetooth® Audio MIDI Dual Adaptor, players can stream music from a mobile device and wirelessly shape tones via the dedicated BTS editor app for iOS and Android.
