When our necks look essentially the same from one to the next we include an Example Photo and we choose the neck for you. Necks that vary a bit more in appearance are often sold as Select-a-Set meaning the one you choose is the one you'll get. You can easily differentiate between these by using the filters on the left and sorting for Select-a-Set or Example Image. The Select-a-Set options also include a 3-digit serial number identifying them a bit more clearly.
