I started playing Weissenborn about 5 years ago. I now have 2 Pogrebas, a shortscale Lazy River, and A 1925 Knutsen. I haven't played a regular 'spanish' style six string in months! I love lap steel. Addictive! As soon as you master dropping the steel down on the string, string muting behind the bar, tremolo and intonation, it's a blast.
