Well its here now and I think it probably is a Mandolin?
On the definites - It definitely is very nicely made with a nice solid spruce top, good tuners, good electrics, good body. It definitely is big and fat, and heavy, (but thats ok so am I), It definitely is only suppose to have 4 strings; this is the way it was made, no alteration of the nut, bridge or headstock. It definitely is a model Q50E there is a nice sound hole label saying so...
But the neck is narrow for a Ukulele much more like a Mandolin and it has a truss rod suggesting that, although it came with nylon strings, it was made to take steel ones? I shall have to ask Crafter what they had in mind when they built it? Whatever it was, its future is to have a new set of Ukulele strings put on and be tuned and played as a Ukulele
No reply from Crafter! (so much for customer service!!) The neck is very narrow for a Ukulele, much more like a Mandolin's neck, so that probably gives me all the answer I'll get? I have tried four different sets of Ukulele strings on it and whilst they work well electrically, (the pickup and preamp is one of the best I have ever used) they don't drive the board well acoustically; quite quiet, a bit buzzy if played hard and no bass. The same volume wise can be said for my Ovation Tenor, (not the buzz though), and that is definitely a Ukulele, (it has a similar bridge too?), but given that I have a set of Mandolin strings I will do a recording with the nylon ones on then swap them for the steel Mandolin strings and see how that sounds.
