    Installation notes:

    The JMASTER™ Set is an active pickup option for Jazzmaster style guitars. The contents of this set allow for a basic control scheme consisting of master volume, master tone, and a three-position toggle switch (not included). The unique upper horn controls (i.e. rhythm circuit) found on many Jazzmaster style guitars will NOT be compatible with the EMG JMASTER™ Pickups, and should be removed or disconnected when installing the JMASTER Set. If you’d like to add a robust active EQ section to your instrument, please consider the EMG JMASTER™ SYSTEM which is available as a pre-loaded pickguard. The standalone JMASTER Set is intended for more basic setups and/or instruments which lack sufficient cavity space for upper horn controls. Please verify that your instrument’s pickguard can accommodate the JMASTER Pickups before installation.
