EMG JMaster System White – WBW Active Prewired Pickguard Set
This EMG JMaster System delivers an integrated active electronics solution in a ready-to-install format, combining Alnico V single-coil pickups with sophisticated onboard controls for immediate tonal flexibility. The multi-laminate pickguard construction reduces microphonics and feedback while the solderless install system eliminates wiring complexity, making this an accessible choice for players upgrading their instrument's electronics.
Active Electronics & Tone Shaping
The system pairs Alnico V pickups with an active preamp circuit that delivers 0.50V output on single strings and 0.80V when strummed, offering controlled, articulate response across the frequency spectrum. The SPC Presence Control provides mid-range boost while the EXG Expander shapes the overall voicing, supported by Master Volume and Master Tone controls for real-time adjustment onstage or in the studio.
Reliability & Quick Setup
A single 9-volt battery powers the system and delivers approximately 400 hours of runtime at 1.20 milliamps current draw, keeping you on the road without constant battery swaps. The 3-position selection switch provides quick access to different pickup voicings, and the solderless install system ensures straightforward integration without requiring soldering expertise—get back to playing fast.
