The H4 is EMG's best selling passive humbucker for guitar. Combining the power of our active 81 with the soul of a passive PAF, this pickup produces a well balanced tone, with tight bass response, glassy mids, and crunchy highs. These tonal features are achieved by utilizing over wound coils loaded with ceramic bar magnets that are fully shielded to reduce noise. This high output pickup is often used in the bridge position where it shines with excellent range, responsiveness, and sweet harmonics. If you want a big rock or heavy modern guitar sound, this is the pickup for you.
