Gadgets

Retro Exterior, Modern Sound

The GB-001 is a high-performance Bluetooth speaker designed to deliver powerful sound. It features independent woofers and tweeters on both sides, creating expansive, full-range stereo audio. Additionally, this model includes a cassette player and recorder, offering analog audio enjoyment with performance comparable to dedicated home cassette decks.

Whether connected via wired input or Bluetooth streaming, the GB-001 utilizes four Hi-Fi class speakers (two woofers for rich bass and two soft-dome tweeters for clear vocals and high frequencies) to produce a total output of 104W.

Beyond power, precise control is essential for superior sound. The device incorporates dynamic power control to minimize distortion, We Are Rewind’s unique sound tuning for a natural and pleasant listening experience, and a spatialization function to create a wider, more immersive stereo soundstage.

Top-Level Recording & Playback Performance

This boombox features a high-performance cassette deck mechanism with internal speed control, which users can adjust to ensure stable playback. For both recording and playback, it supports Type I (Normal) and Type II (Chrome) cassettes, with optimized bias adjustments for excellent sound quality. An active AC erase head is employed to suppress noise and achieve superior frequency response during recording.

Two backlit VU meters, reminiscent of classic audio equipment, are also included, allowing visual monitoring and control of playback and recording levels. Furthermore, an adjustable microphone input terminal is provided, enabling live recording.

The classic rectangular design integrates symbolic elements of boomboxes from that era, including woofers, tweeters, a cassette player/recorder, VU meters, and a foldable handle.

Beneath its retro exterior, the GB-001 is equipped with the latest technology, including Bluetooth 5.4 and a rechargeable battery, making it a modern “2.0” boombox.
