Last year, on behalf of two pipers in our band, I purchased a set of AB4's, blackwood mounts, one with celtic engraving, the other in this lovely pattern. The quality of manufacture and sound is superb, the service and support excellent, and the pipes are easy to reed and play. The Victorian engraving is very attractive, and the new alloy is threaded and does not tarnish, which was an issue with older McCallum pipes. With mounts and ferrules now threaded, the pipe is a great purchase for any player.
