We will be receiving our new shipment of these very special wires very soon! We talked to Canopus direct after our endorsees requested for more ‘buzz’ when they tune their snares low: the whole gang of them! We heard you all right. These wires are only available as upgrades when you build a custom snare with us and are not for sale…:) As advertised, these wires give a really powerful sound and projection at all volume levels. You should try it for yourself…:)
