    Boss ME-90 Guitar Multi-Effects Pedal: Tone Power without the Menu Diving

    The BOSS ME-90 guitar multi-effects pedal is what happens when decades of BOSS engineering meet the attention span of a modern guitarist. It’s compact, road-ready, and unapologetically hands-on. Just twist, stomp, and play. Whether you’re dialing in lush reverbs, face-melting distortion, or punchy mod effects, the ME-90 puts everything at your feet.

    Built on the bones of the legendary ME series — and now souped up with flagship-grade AIRD amp modeling, IR loading, and GT-1000-class effects — the Boss ME-90 is the most advanced model yet. And if you're tired of tap dancing across a dozen stompboxes just to get a decent lead tone? Congratulations. You’ve found your upgrade.

    Boss ME-90 Multi-FX Powerhouse

    What’s Under the Hood? A Whole Lotta Tone

    The Boss ME-90 guitar multi-effects pedal isn’t just crammed with features — everything’s laid out in front of you, ready to twist, stomp, and shred. Here’s what makes the ME-90 the most gig-friendly, jam-approved, tone-stacked pedal in the Boss family:

    • All-in-One Multi-FX Powerhouse: Over 60 premium effects and 11 AIRD amp models pulled straight from the GT-1000’s DNA.
    • AIRD Amp Modeling + IR Loading: Get real amp feel and tone with advanced AIRD tech, and load in up to 3 custom IRs for your own cab flavor.
    • Pro-Grade Audio Quality: 24-bit AD/DA, 32-bit floating point processing, and 48 kHz sampling rate means what you play is what you hear — only better.
    • Manual Mode & Memory Mode: Switch between pedalboard-style control and full patch recall depending on how much brain power you’ve got left mid-set.
    • Eight Footswitches + Expression Pedal: Real-time control at your feet, including a redesigned expression pedal with a toe switch for wah, volume, or chaos.
    • 36 Presets + 36 User Slots: Enough space to cover every genre from country twang to death jazz and everything in between.
    • External Loop + Output Optimization: Send/return loop for your favorite drive pedal and output mode switching for amps vs. PA rigs.
    • USB-C Audio & MIDI: Record directly into your DAW or edit patches using BOSS Tone Studio.
    • Lightweight and Battery-Powered: Under 7 lbs, four AAs, or an optional adapter. Take it anywhere.

    Deep Editing. Seamless Control. Welcome to Tone Studio.

    Although the ME-90 gives you full hands-on control straight out of the box, sometimes you want to go a little deeper, like surgically swapping out amp models, loading your own speaker IRs, or fine-tuning parameters that are hiding just beneath the surface. Just download BOSS Tone Studio.

    Connect the Boss ME-90 guitar multi-effects pedal to your Mac or Windows-based PC via USB-C, fire up the Tone Studio software, and suddenly you’ve got a bird’s-eye view of your entire sound rig. You can edit every patch, tweak EQ curves, assign footswitches, drag-and-drop effects in your chain, and even load up to three custom cabinet IRs with the ME-90 IR Loader. It’s like turning your pedalboard into a modular synth.

    You can also save and organize your favorite patches, back them up before gigs, or download new ones from BOSS Tone Exchange when inspiration hits. And yes, you can do all of this while the ME-90 stays live and playable.
