#8/12 degree. According to their chart, #8 should be .120. I'm happy with the Level Air but was just curious, and I got a ridiculous price. If it can be a little more mellow yet have big lows and clear highs, I would be happy. I have two necks - 1 with a thick cork for the Level Air and 1 with a thinner cork for smaller bores, so I'm ready to try some pieces.
