about 2 and a half row G/D boxes
I already play B/C and need even more pain so I’m considering getting a 2.5 row G/D. Please can anyone tell me whether any maker supplies such boxes with the extra notes D, G# and F natural (over a couple of octaves) on the draw? (my idea, perhaps naive, is to be able to play entire scales for keys C, G, D , A major and related minors on the draw). Cheers.
