Anyone ever use the Dunlop JD Jazz Tone picks? I have been using the 205 and the 206 models for a few years and really enjoy them. They aren't graphite like the Adamas or Telefunken but they are non-flexible beefy picks. These two models are teardrop shaped. An exceptional guitar player I know got me hooked on these. He said they drastically improved his tone and they were pretty cheap so I ordered a bag of each. These little picks really hold their structural integrity for a good while. I do miss the graphite feel and can tell a slight altering in tone. Anyone tried the teardrop version of Telefunken?
