Wishing you all a very Merry Christmas and the best for the New Year. As we come to the end of a hectic, frenzied roller-coaster of a year, I want say a big thank you to all the guitarists, musicians, audio engineers, customers, suppliers, and every person I’ve had the privilege of working with. Your support, collaboration, and encouragement is what makes my little company possible — and for that I’m genuinely grateful. Thank you. Have a great holiday and see you on the other side in 2026!
