Gemini Sound GTR-400 portable retro Bluetooth speaker and guitar amp — 90W peak, dual 4.5" woofers, 10-hr battery

The Gemini Sound GTR-400 is a portable Bluetooth speaker that doubles as a personal PA — plug in a guitar or mic, wrap the strap over your shoulder, and go. With 90W peak through dual 4.5" woofers and a 1" tweeter, it's loud enough for the living room, the back porch, or a street-corner jam. Retro looks, real sound, and everything you need built in.

Key features

• Speaker and amp in one — Two inputs for mics or guitars with their own volume and reverb controls. Practice, busk, or host an acoustic set without hauling a PA.
• Plays from anything — Bluetooth from your phone, tablet, or laptop. Plug in over aux, USB, or SD card when you'd rather go wired. Dial in the sound with bass and treble EQ.
• Take it anywhere — Up to 10 hours of battery and an included shoulder strap. Recharges off the adapter when you're done.
• Real bass for its size — Dual 4.5" woofers and a ported enclosure push more low end than you'd expect from something this compact.
• Retro style that fits anywhere — Analog knobs, tweed grille, and a shape that looks at home on a shelf or on stage.
