Nagra QGB // Vintage / 10.5" Reel Adapted for Nagra IV-S, IV-SJ (S/N: 46)

The Nagra QGB is one of the coolest and most coveted accessories in the Nagra ecosystem—a brilliantly engineered 10½-inch reel adapter that transforms a compact Nagra IV-series recorder into a full-size mastering machine. Built with the same Swiss mechanical precision as the recorders themselves, the QGB adds external reel motors, tension arms, and guides that integrate seamlessly with the Nagra’s transport, allowing it to handle large NAB reels with rock-solid stability.

For archivists, tape enthusiasts, and anyone transferring or mastering from big reels, the QGB is a total game-changer: smooth tape handling, quiet operation, and that unmistakable Nagra elegance in motion. Paired with an IV-S or IV-STC, it becomes a miniature mastering deck—beautiful to watch, incredible to use, and a must-have for anyone who appreciates analog craft at its highest level.
