Description Our MM4 4 string bass humbucker was originally produced for my departed friend Jimmy Loyd Rea, USA bassist of great reknown. Jimmy is in the Blues Hall of Fame and played with the likes of BB King, Muddy Waters etc so when it comes to a great sounding bass he really knew his thing. This bass humbucker pickup has a resistance of 12.86 kOhm but more importantly puts out 6.16 Henries of inductance, the true measure of the power of a pickup. Alnico 5 slugs are used to provide the magnetism. Unlike a lot of heavily overwound pickups, both bass and guitar, by careful winding and magnet matching the pickup has wonderful low frequency responses without sounding dull and lifeless. If you have a look at the frequency response chart shown you can see how it is very easy to exactly tune the level of bass you are after by using various tone capacitor values so that you get that extreme bass punch right in the chosen frequency ranges. The chart shows the response of the pickup with both humbucking coils wired in series but as this is a 4 wire output harness pickup you can switch it from series to parallel or coil cut it down to a single coil mode which will enahance its treble responses. The wiring harness colour codes go like this. Black = start / negative of coil 1 – South pole White = finish / positive of coil 1 Red = start / negative of coil 2 – North pole Green = finish / positive of coil 2 String spacing on this 4 string bass humbucker overall is 57mm. That means between each string its 19mm. The pickup comes pre-wired in series with the red and white wires, that link the two coil banks, ready joined. The pickup is also wax potted and resin sealed. Warman® Guitars produces high-value humbucker and single coil pickups designed for guitarists who want powerful tone, reliable electronics, and upgrade-level performance without boutique pickup prices.
