Description
Quick Product Summary
The BOSS ME-25 is a compact guitar multi-effects processor that combines a wide selection of effects, COSM amplifier modelling and hands-on controls in a rugged floor-based unit. With overdrive, distortion, modulation, delay, reverb and pedal effects all onboard, it provides an extensive range of sounds without the need for a large individual-pedal setup.
This used example is in Good condition, showing signs of previous use consistent with a pre-owned floor processor. Its built-in expression pedal, Phrase Loop function and straightforward Sound Library make it equally useful for practice, recording and live performance.
What Makes the BOSS ME-25 Special?
The ME-25 combines BOSS effects with COSM amplifier modelling, covering everything from clean and vintage-inspired amp sounds through to modern high-gain tones. Its Sound Library provides quick access to ready-made sounds across Clean, Crunch, Drive, Heavy, Lead and Extreme categories, while Drive, Tone and Level controls make editing straightforward.
A built-in expression pedal provides real-time control over effects including wah, octave and Freeze, while the 38-second Phrase Loop allows sound-on-sound recording for practice or performance. USB connectivity also enables the ME-25 to function as an audio interface when connected to a compatible computer.
Who Is It For?
The ME-25 is ideal for guitarists who want a broad selection of effects in one portable unit. It is particularly well suited to home practice, rehearsals, recording setups and players who want to experiment with different amplifier and effects combinations without building a large pedalboard.
