Seymour Duncan TB-APH1B Alnico II Trembucker RevZeb Pickup

Seymour Duncan TB-APH1B Alnico II Trembucker RevZeb Pickup

The TB-APH1B delivers articulate, dynamic response with a moderate output character that rewards precise picking technique and maintains clarity across the frequency spectrum. Built by Seymour Duncan's Santa Barbara workshop, this Alnico II trembucker bridges vintage warmth with modern definition, making it a solid choice for players seeking balanced aggression without excessive gain—whether you're tracking in the studio or pushing it live night after night.

Tonal Character & Electrical Performance

The 6.7 kHz resonant peak and 7.85 k impedance create a midrange-focused response that cuts through dense mixes while preserving articulation in fast passages. With 8.8 DCR in the bridge position, this pickup maintains harmonic complexity and string-to-string definition across a wide range of playing dynamics—essential for staying locked in with a full band or heavy riff work.

Construction & Configuration

The dual-coil humbucker combines an Alnico 2 bar magnet with a nickel silver bottom plate, then potted in wax to eliminate microphonic squeal and ensure consistent performance under stage conditions. The F-Spaced trembucker design (2 1/16" E to E) accommodates modern wide bridge spacings while maintaining proper string alignment and reliable output night after night.
