Gemini 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.
