Re: Can you tell me if this is a Cool rail or a Hot rail
That looks like a Cool Rails to me. Its one of the older versions. The older Hot Rails would have had a triangular lip on the baseplate as opposed to the oval plate you see in the pic. A Hot Rails could have been custom ordered without the lip, I suppose. But, the older codes for a Hot Rails neck would have just been the "n" while the Cool Rails has a "1n" code. Duncan has them listed as being wound for the neck at 10.8 for the Hot Rails and 9.4 for the Cool Rails.
