JJB Electronics is a US-based maker of surface-mount piezo pickup systems for acoustic stringed instruments. The company specializes in passive transducer sets that attach to the inside of an instrument's top and pick up vibration through the wood itself, rather than mounting under the saddle or inside the soundhole. A proprietary potting material around each transducer is used to dampen harsh piezo harmonics while preserving feedback resistance.

The core catalog centers on the Prestige series of acoustic guitar pickups, including the Prestige-330 (a three-transducer passive system), the Prestige-220, the Prestige-110, the Prestige-430c, and the Prestige GS-330 tailored for the Taylor GS-Mini. The company also offers systems aimed at other instruments, such as the PB-200 and PPS-200/PPS-100 for ukuleles, mandolins, banjos and violins, and the DB-400 for upright bass. Accessories include the Voljack volume-control endpin jack and the JP1 preamp.

JJB Electronics occupies a niche in the acoustic pickup market favored by players looking for an inexpensive, DIY-installable alternative to under-saddle or soundhole-mounted systems. The Prestige-330 in particular has been reviewed favorably by Guitar World and is a common recommendation on acoustic-guitar forums for players seeking a natural amplified tone from flat-tops, classical guitars, and smaller-bodied instruments.

JJB has 1 product cataloged on Equipboard, including Acoustic Guitar Pickups.
