The Glockenklang Double. Just received it yesterday. People - words cannot begin to describe the sound of this cab. It is the smoothest, sweetest thing I have ever heard. And I converted from a Bergantino HT322. I had been using a Heart-Rock head through the Berg, so I knew what Glock was about, but this cab has exceeded any expectations I could have even began to think about conceiving of. It's like hearing the bass for the first time. It is smooth, refined, clear, responsive, warm, just beautiful. I really don't understand why anyone would use anything else. You've got to hear these things. Take a trip if you have to. It's worth it. Or heck just order one! You won't be disappointed.
