I have one MB Deluxe that was specially made for me. I do quite like it but I spent hours tweaking it to get good response. I haven't bought a Rocket because it costs a bomb. They brought it out after discontinuing the SP20 low D, a very sad day. I bought two Seydel Session Steels and neither of them survived the first session I took them to. A friend had exactly the same experience. You'll need that friendly service centre a lot. The double-sided Hohners are inexplicably in blues harp tuning, which means s a missing sixth in the bottom octave. And they're pinned together!
