Emilio is a good man. He is old country, not just old school. His reputation is well deserved and has earned the respect of international woodwind luminaries through several generations. I have had the pleasure of doing business with him for ~32 years and trust him like a close family member.
He will honor what is honorable. He will see through someone trying to take advantage of him.
The "lifetime" warranty? I bring my Super 20 and Mark VI into him occasionally and he makes necessary adjustments. The Super 20 has already been overhauled by him twice, so it's in it's second "life." He mentioned that it will be good for another year or so without needing a new overhaul. It is my workhorse, it can't stay perfect forever.
I try to get into Rayburns ~ once every month or so. If I don't have my tenors with me, he requests to see them at least 2-3 times a year for a check-up.
Long live Don Emilio!
