Middle, alnico Noiseless Single Magnetic 13,9K 

The ASN57 is a noiseless version of our vintage style AS57. The ASN57 retains the classic vintage sound of the AS57 by using the same full size sensing coil with the correct gauge of winding wire and full size AlNiCo V magnets. The smaller noise cancelling coil is placed below the sensing coil to remove the noise without compromising the tone.
