オプティマ コブレ ソプラノ D ホイッスル（チューナブル）

Got it today and started playing ASAP. The tone is sweet, clear and sweet. The jump to the upper octave is quite easy. It just sounds perfect. A pleasure to play. It's also gorgeous. I've never had a copper whistle before. I love that. I'm not an expert but maybe that's a reason for how good it sounds. This is now my go-to whistle, along my Wild Irish.
