Wowwwwwwwww, finally got my Glockenklang Duo 2x10 cabinet today. I already owned a 1x15 Uno Rock Deluxe which I used together with my Schroeder 1210. While the Uno and 1210 combo worked very well I got today into the true Glockenklang heaven. I used to visit some German stores about ten years ago that carried Glocks and was truely impressed by their tone. But I used the Epifani rig these days and it felt kind of snooble to change a super good rig to a fantastic one. But boy was I happy to finally get that complete Glockenklang rig. My MTD535 sounds super great through a Quantum 600 head and 2x10+1x15 Glock rig. Every note is really clear and musical and warm at the same time. Wow, just wow!
