ah, the ubiquitous a5. my fave alnico flavor. the coil shape/size also plays a part, where squat tends to favor midrange and tall the treble side. then there's the turn count, where 10k turns of 42awg pe will definitely spew more midrange (that's "fat") than most tele bridge pups, and is quite comparable to the duncan broadcaster. next time, try 11k turns of 42awg fv or pe coil wire - that will be an ear opener.
