I have not played a Black Beauty but I owned its cousin, the Basic Black. It was a fabulous sounding combo that still ranks among the best I've ever owned. Unfortunately, it developed some real reliability issues as did my friend's Basic Black - after I convinced him to buy it
I've also heard Redhead and other combo models and they all sounded great. Hopefully the reliability issues we encountered were just co-incidental freaks of nature. Might be a good idea to search on Black Beauty repair issues, but I'm sure the sound is terrific.
