I have the Morillo Latin Guitar. It's no more than OK. I looked at the ebay Morillo baroque guitar, but for the same price you could get a vihuela by Alexander Batov, one of his plain vihuelas in B or A (an A vihuela was very common) or for a little more, a plain vihuela in G. His plain vihuelas have little in the way of decoration, but they are structurally the same instrument. http://www.vihuelademano.com/vihuelas/pages/flatbackA/flatback_vihu...
i checked out Alexander Batov's site http://www.vihuelademano.com/guitars.htm and he does have simpler flat backed guitars for under £2000, which is at my extreme limit , but possible ; (his workshop, which I have never visited, is not too far from me) My guess is that a Batov would be distinctly better than a Murillo, but that the latter would be fineas an introduction to the instrument. (Rob - I just listened to you playing Sanz on a Batov guitar, and the sound really is exquisite.)
I've just uploaded a video here of the Morillo so-called Latin guitar in action. Wire strings are a nightmare to tune, but otherwise it was an enjoyable experience playing it. The bridge has a metal bar in it, presumably because of the wire strings. Not a baroque guitar, but it might give you some idea of the quality of the instruments by Morillo.
Marcos replied in a very friendly and informative manner. He is very pleased to know he has been recommended here . He has 3 BG models - the Spanish (Mallorca) model, the Verboam/French and the Sellas/Italian. Could anyone describe how different these might be to play?
