"All twelve keys"

Hmm. My favourite brand, Suzuki, don't make them below low F. For years I used Hohner Special 20s in low D, great for Irish tunes, then they stopped making them, "replacing" that model with one that cost nearly three times as much. Humph. But I hear that, from early next year, Lee Oskar will be making low-tuned harps down to low D, costing the same as their standard harps. Oskars are known for being bomb-proof ((almost!), and they play nice as long as you're up for a touch of tweaking, so I'll be treating myself. Someone is sure to mention "another" brand that does low keys. If you PM me I'll tell you why you shouldn't buy one!
