I've had two Johnson single cone steel bodies. They both were junk. Lay one of those babies up beside a real National and you quickly realize they don't sound nowhere close. Beware of on line reviews. Some of them are put up by people selling them. Quality on them is hit or miss since they are made in China but has improved some. Most all the cheapies can be improved by installing a quarterman cone, though. National cones don't sound as good as a quarterman in single cone. I have Johnson tricone also and it sounds great but i've modified it some and changed cones to Nationals. They are made by AMISTAR in Checzoslovakia and i would say they are worth the money($1100 US). May i suggest a cheaper Dean or Regal steel body? I have a Dean and it's the one i grab most of the time. With a quarterman and maple/ebony bridge it has a vintage sound that rivals a real 1930's National. Sounds like about halfway between a Duolian and Style O. The Regal is the exact same guitar(korean made in same plant)and sounds the exact same as a Dean, except with a different headstock and they go really cheap on ebay. The quality, playability, and finish is 10 times better than a Johnson. My opinion anyway, and i've played all of them(slide).
