The Mustang Micro is a tiny headphone amp that plugs directly into your guitar's output jack — no cables, no desk, no amp required. Despite fitting in the palm of your hand, it packs 12 amp models and 12 effects drawn from the full Mustang GT series, which means you can get convincing clean Fender tones, crunch, and even high-gain sounds, all silently through headphones.

Battery life runs around four hours on a charge, and it connects via Bluetooth to the Fender Tone app for adjusting presets from your phone. There's also a 3.5mm aux input so you can play along with music. If you live in an apartment, practice late at night, or just want to noodle without disturbing anyone, the Mustang Micro is one of the most practical tools you can own.
