B/1820 Treble Bass Booster
The G.I.S. B/1820 Treble Bass Booster is a quintessential piece of vintage Italian tone magic. Produced in the late 1960s by the pioneering effects company JEN Elettronica, this compact plug-in preamp module packs a powerful punch, letting you sculpt your guitar's voice with surgical precision. Sharing the same circuit as the legendary Vox V8401, the B/1820 is a transistor-based tone sculptor that connects directly to your guitar, boosting either the treble or bass frequencies to dramatic effect. Dial in a touch of chime and clarity for shimmering clean tones, or fatten up a thin signal with a rich, creamy low-end boost - the choice is yours. What makes the B/1820 so special is its incredibly smooth, musical response. Unlike some boosters that can sound harsh or artificial, this Italian marvel maintains the natural harmonic character of your guitar, simply enhancing and refining your tone. The single rotary control allows you to seamlessly sweep between treble and bass emphasis, giving you real-time control over your sound. Housed in a compact, durable metal enclosure with a timeless vintage aesthetic, the B/1820 was used by countless European guitarists in the late 60s and early 70s, from session aces to rising stars. Its plug-and-play simplicity made it a go-to tool for quickly sculpting your tone, whether in the studio or on the stage. If you're seeking a vintage booster that can breathe new life into your rig, the G.I.S. B/1820 Treble Bass Booster is a true hidden gem - a piece of Italian audio history that will transform your guitar's voice with its smooth, musical magic.
