I read on Dave's website that he uses (along with an Underwood) an AKG 406c mic mounted on the tailpiece. I did some research but could not find the AKG 406c anywere leading me to believe that it is no longer made. What type of mic is this? I know it is a condencer but is it a small one similar in size to a K&K Golden Bullet or is it a larger mic that he just somehow attacked to his tailpiece?
