Just got a custom flute head joint from Kessler's music for $200 brand new. They are solid silver and were re-cut by master maker Chris McKenna. All of a sudden all three octave ranges on the flute just pop out. I wasn't having any luck before. Suzy asked me why I bought it, so I had her try her stock gemeinhardt head and then try the McKenna. Better sound, more volume and wow! So I ordered the last one Dave Kessler had for Suzy. I've always heard what custom heads can do for a flute but I hadn't really bought into spending the money to find out. For $200 though, I got a steal of a deal and Dave's not gonna do any more of these. Funny thing, three of the flutes in the WCB want to try the head now. Too bad they aren't available anymore.
