Boss ME-90 Guitar Multi-Effects Processor

The Boss ME-90 is the most advanced ME model to date. It offers exceptional audio quality with 24-bit AD/DA and 32-bit floating point processing. Also, it has flagship-grade AIRD amp models, IR loading, an effects loop, and more.

The Boss ME-90 is a premium compact, battery-powered and versatile all-in-one processor, that includes easy-to-build, customizable sound setups. The BOSS ME series has been a favourite of performing guitarists for three decades.

Fast Sound Creation

With its knob-driven interface and diverse effects selection, the Boss ME-90 Guitar Multi-Effects Processor lets you build configurations and tweak tones with the ease. Because of its knob-driven interface and diverse effects selection, it avoids the hassle of fastening tape, power distribution, and multiple connection cables.

Just dial up an amp model or effect type within a category and turn the knobs to get the sound you want. There are 36 preset patches with ready-to-play pro tones, plus 36 user patches for storing your custom creations.

ME-90 Flexible Real-Time Control

The ME-90 features eight footswitches with smooth, quiet operation and an expression pedal with an integrated toe switch. Use Memory mode to call up complete patch setups with the footswitches. Afterwards, switch to Manual mode for direct on/off control of each effect category within the patch.

The footswitch LEDs light in different colors for quick identification in the heat of a performance. It’s also possible to set all LEDs to light in a fixed color for each mode if desired.

High-Quality BOSS Effects

The Boss ME-90 Guitar Multi-Effects Processor puts a massive library of BOSS effects at your command. It offers seven different categories filled with selections derived from the flagship GT-1000. Everything you need is here, from overdrives and distortions to pitch/mod effects, delays, and high-quality reverbs.

You also get 11 dedicated Pedal FX, a looper, and specialized effects such as acoustic simulation and down tuning. There are 60 effect types in total, with access to over 20 more via BOSS Tone Studio. A send/return loop is available for external pedals. They’re complete with the ability to save the on/off status in patches. Also, place the loop before or after amp models in the signal chain.

Premium Amp Sounds with AIRD Technology

Along with its effects, the Boss ME-90 includes amp models ported from the GT-1000, driven by our advanced AIRD technology for authentic tube tone and touch response. Eleven onboard amp types offer everything from clean combo sounds to punishing high-gain stacks, and you can access more selections in BOSS Tone Studio.

Each amp includes a dedicated cab sound for connecting to a PA or recording device, and you can load three of your favorite speaker IRs to personalize sounds to your taste.

Edit, Customize, and Expand

BOSS Tone Studio for macOS and Windows extends your creative range. It allows you to edit tones and change out some amp and effect types with alternate selections. In addition, you can save and organize patches for different gigs, download pro setups at BOSS Tone Central, and swap patches with the ME-90 community on BOSS Tone Exchange.

The ME-90 also supports the optional Bluetooth® Audio MIDI Dual Adaptor. It enables you to stream music from a mobile device and wirelessly shape tones using the dedicated BTS editor app.

Light, Durable, and Ready to Travel

The ME-90 is lighter than its previous generation model while maintaining the rock-solid durability that BOSS is famous for. The expression pedal has been newly redesigned as well for even finer parameter control.

You can power the processor with four AA batteries. Otherwise, use an optional AC adaptor. Also, a rear-panel switch instantly optimizes the outputs for use with a guitar amp or a full-range sound system such as a PA. Along with BOSS Tone Studio communication, the USB-C output allows you to use the ME-90 as a computer audio interface for your go-to music production software.
