BOSS ME-90 Guitar Multiple Effects Processor

BOSS ME-90 Guitar Multi-Effects Processor with AIRD Amp Modeling

The BOSS ME-90 Guitar Multi-Effects Processor delivers 97 effects types and 11 AIRD amp models ported directly from the flagship GT-1000, all housed in a compact, battery-powered floor unit. Whether you need overdrives, delays, reverbs, or acoustic simulation, the ME-90 puts professional-grade tones at your feet with the hands-on simplicity of a traditional stompbox setup.

For gigging guitarists searching for the best all-in-one guitar processor, the ME-90 eliminates the complexity of a traditional pedalboard — no power distribution, no signal chain puzzles — while delivering the tonal depth that working players demand. Its dual operating modes let you call up complete patch setups via Memory mode or flip to Manual mode for direct per-category on/off control mid-performance, making it equally capable in studio sessions and live environments.

Built on BOSS's advanced AIRD (Augmented Impulse Response Dynamics) technology, the ME-90 achieves authentic tube amp touch response and dynamic behavior without a physical amplifier. The 24-bit AD and 32-bit floating-point processing chain ensures studio-grade audio fidelity, while the USB-C output doubles as a computer audio interface — connecting the ME-90 directly to your DAW for recording. Speaker IR loading via the ME-90 IR Loader software adds further tonal personalization, and the optional Bluetooth Audio MIDI Dual Adaptor enables wireless editing and audio streaming from iOS and Android devices.

Key Features of the BOSS ME-90 Multi-Effects Pedal

• Flagship AIRD Amp Models: Eleven onboard amp types — from clean combos to high-gain stacks — deliver authentic tube tone and touch response drawn from BOSS's GT-1000 flagship processor.
• 97 Effects Types Onboard: Seven simultaneous effect categories cover compressors, overdrives, modulation, delay, reverb, and specialized effects including acoustic simulation, down tuning, and 11 dedicated Pedal FX — with access to additional types via BOSS Tone Studio.
• Intuitive Knob-Based Interface: Stompbox-style controls let you dial in sounds in seconds without menu-diving, making real-time tone shaping fast and natural whether in rehearsal or on stage.
• Dual Performance Modes: Memory mode enables instant patch recall across eight footswitches; Manual mode provides direct on/off control of each effect category within a patch for flexible live performance.
• User Speaker IR Loading: Supports up to three custom speaker IRs via the ME-90 IR Loader software for Windows and macOS, enabling personalized cab sounds when connecting to a PA or recording interface.
• USB-C Audio Interface: Connects directly to music production software for recording and playback, eliminating the need for a separate audio interface in practice or home studio use.
• Send/Return Effects Loop: Integrates external pedals into the signal chain with patch-level on/off control and flexible pre- or post-amp placement — preserving your existing pedal investments.
• Battery or AC Powered: Runs on four AA batteries (approximately 6.5 hours) or an optional AC adaptor, making it a self-contained solution for busking, rehearsal, and travel.
