These are for a 7-string MULE. The wiring length is approximately 19cm for the rear and 13cm for the front. The resistance values are approximately 7.48 for the front and 8.37 for the rear. The holes have been expanded for direct mounting. If you like a clear and flat sound quality, these are perfect. They have been used, so there are scratches, but there is no rust and they are relatively clean. Please refrain from purchasing if you are sensitive to such things. I am not considering lowering the price.
