How nice to hear that they are still serious technicians out there. :|I use Matt Stohrer who is located in North Carolina. For my money, he is an AMAZING tech and wonderful to work with. He did my old YTS61 and has my Keilwerth SX90R in his shop now. My old 61 is better than it EVER was and I've been playing it and loving it for about 23 years. You can contact him at stohrermusic.com. He is an incredibly knowledgeable tech and a terrific human being to boot. Best of luck!
