Funny company Dimarzio, they seem to think getting patents for absolutely everything including fresh air and colours mean their p/ups will sound good-the only thing that makes a pickup sound good is patience, attention to detail and using you ears when voicing and not theory. Obviously I personally believe handwinding and scattering the wire plays a big part too.
Glad the Mules are doing it for you Ron, they're my favs too, I find I can get just about anything I want from them and they always sound HUGE!
