Powerhouse FX with Stompbox Simplicity

The affordable new ME-25 is packed with powerful BOSS features to make you sound like a pro, yet it’s as fun and easy to use as a stompbox. The built-in SOUND LIBRARY gives you instant access to dozens of classic and modern effects. Simply choose a category, select a variation, and play. Customize your sound with simple twists of the Drive, Tone, and Volume knobs. With COSM amp models onboard, plus Super Stack and Phrase Loop, the ME-25 is a dream processor for upstart guitarists who want great sound and ease of use.

Instant Access

The sleek, black and white design of the ME-25 makes each button, knob, and pedal easy to see and access. Three footswitches, an Expression pedal, four knobs, nine backlit buttons, and enlarged LED panel provide an uncluttered control panel that’s great for any environment — even on dark stages.

COSM Modeling

Its price might imply “entry level” but the COSM-driven ME-25 is nothing but first class. Exquisite amp models derived from the deluxe ME-70 cover a wide stylistic landscape, from classic to contemporary. The new ULTRA METAL offers screaming hi-gain distortion for all kinds of metal music. Included in the tone palette is SUPER STACK, which, with one press of the dedicated button, makes a small practice amp sound like a monster stack.

Customizable SOUND LIBRARY

Dozens of ready-to-use presets are built into the ME-25’s onboard SOUND LIBRARY, all quickly selectable by category, but you can easily customize the sounds with the dedicated front-panel knobs. Free downloadable Librarian software also lets you edit and save your sounds easily and conveniently onscreen.

USB Connect

Connect the ME-25 directly to a PC with a USB cable and you have a personal recording studio at your fingertips. The ME-25 can function as a USB audio interface, which creates a convenient, consolidated studio setup with Cakewalk SONAR LE software (available for free). BOSS TONE STUDIO librarian allows you to download extra patches directly from the BOSS TONE CENTRAL website.
