From Canopus' website:
"Snare wires which enhance even the subtleties of nuances in the midst of very loud back beats! By adopting spiral wires with an abundance of coils coupled with 1mm end-plates, we have achieved a good balance between volume that is aggressive enough for a powerful back beat and swift response for delicate phrasing. With this one snare wire, you can have an aggressive, loud snare sound and maintain sensitivity.
These snare wires create a loud attack and sharp response even for ghost notes. Very effective for wood-shell snare drums.
These snare wires have both a loud attack and bright sound. They have an enormous effect on metal-shell snare drums. They will improve the potential of a loud snare tremendously.
