This little brute was designed to impart the warm, smooth tone of an old Patent Applied For humbucker in a direct replacement, single-coil size. It possesses an even, dynamic response, and its adjustable pole pieces allow the guitarist to fine tune the string balance and dial in just the right amount of punch. Compared to the JB Jr., it has less output and more upper-mids. Comes with four-conductor hookup cable. Available for both bridge and neck/middle positions; and in an incredibly versatile set with an SJBJ-1b JB Jr. in the bridge, an SDBR-1n Duckbuckers in the middle and an SL59-1n Little '59 in the neck. For all well-balanced instruments. Works equally well with maple and rosewood fingerboards.
