I bought a Gabbi in G thinking it would be good for singing but in the majority of cases the C box wins and I'm no virtuoso singer. The only real joy I've had is being able to sing Bonsoir Moreau, otherwise its a dreary sound and lacks the liveliness of a C, not bad for low down dirty blues though to be fair.
Thinking I'll get C hohner reeds put in as I like the box and I've sold my 114. If SOTM gets resurrected I'll post a tune on G Gabbi as its' my main player at the moment.
