This modern Gibson classic features tonal characteristics similar to the '57 Classic, delivering a slight increase in the upper mids, for a more contemporary humbucking sound. The special Alnico II magnet gives this beauty a singing quality that delivers on demand. The 490R guitar pickup, with its neck-spaced pole pieces, is calibrated to perfectly match the bridge-spaced 490T. It comes with 4-conductor shielded wiring for series/parallel/split coil variations.
