This year, I officially became a proud member of the SEYDEL Harmonica Company, who manufacture and design some of the most innovative Harmonicas in the world. I have long been a fan of their amazing Chromatics, and am proud to now be included in the SEYDEL Endorsee group. Their instruments are designed and built in Germany, and they are one of the oldest and most prestigious Harmonica companies in the world. I am especially fond of their newest Chromatic Harmonica, called “The Volcany”, an all-brass beauty that is truly a blast to play. I’m also a huge fan of their “SYMPHONY” line of chromatics, and the ever reliable SAXONY Chromatic Harmonica. 

The people are SEYDEL are true music lovers, and really support the artists they endorse.

“Jason Keene’s great Chromatic playing is only exceeded by his expertise and knowledge of the Lekholm DM48.  He has tutored and fast tracked me on the DM48 for which I am forever grateful.”

“As demonstrated in his many excellent YouTube videos, Jason Keene knows the wonderful Lekholm DM48/48X Midi Harmonica intimately. Both as an expressive jazz player and in his understanding of how best to set up the instrument with Midi devices, his knowledge of how everything works together is unrivaled. Besides, he’s a really friendly guy who is happy to share his hard-won insights! It all adds up to making him an excellent teacher, who can quickly short cut the learning process to get you enjoying your DM48/48X in the shortest time possible.”
