Kamelot have posted the following message on their official Facebook page

"We are sadly sharing the news of the passing of our close friend and brother, Kyle Sabel. Anyone who knew Kyle knew he had a big heart and had your back whenever you needed him. We are all so heartbroken over this news. Kyle has been a huge part of the Kamelot family since 2005 as our guitar tech and all around awesome stage manager and protector. The past few months he has been suffering from some serious health issues. Kyle was a great friend and co-worker and will be truly missed. Our thoughts and prayers are with all his friends and family. Rest in peace, brother."

Guitarist Chris Caffery (Savatage, Trans-Siberian Orchestra) has also posted a heartfelt tribute Sabel:

"For 16 years I had the privilege of having the most bad ass guitar tech on the planet. Not only was he my tech he was my friend. Truly my brother. I spent the last 16 Halloween, Thanksgiving, Christmas and New Years with Kyle. While most other people were home with their families, we were together somewhere in the world in some hotel being each other's family. Kyle was the guy everyone turned to when life at home wasn't the rosiest or life's problems caught up with you. He made the days on and days off a lot easier just by always being able to make us smile and laugh. Many times when he was crying inside.

Many people knew and loved Kyle. He was one of the funniest and nicest people I had ever known. He was what we always considered a great road guy. Meaning he did his job well but he also always made people smile. Made people who were away from home at the holidays feel like they were home. I did over 1000 shows with him as my tech and I think maybe something went wrong w my rig 3 times. And it was never his fault! I may have been out of tune less times than fingers on one hand.

Every single guitar I had built for me it would be a constant text communication about specs, colors, pickups...then what straps would I use and what guitars do we leave home this tour. There were a couple guitars that he was like. 'When we retire that's mine...' Playing those will have a new meaning from now on!

Far beyond my guitars and that stage he was my friend. We laughed and cried together for almost two decades. We mourned the loss of our friends, band mates and families together. We never once so much as even had a single argument.

Other than my own mother, Jon Oliva, Igor, Jeff Plate and my own brother I have not spent more time with any single individual in my life. It's really hard to express exactly what I'm feeling right now but there will definitely be a huge void in many people's lives with Kyle gone away with the Angels."
