Dear all, if problem is changes in humidity and/or temperature when the instrument gets out from the case, why not letting the instrument all the time out from the case? My two lutes "live" outside their cases, permanently. I must say that humidity here in Barcelona is nearly always quite high (around 60-80%). This is not Madrid or New Mexico...
Regards, Manolo Laguillo Barcelona I have heard that Jordi Savall has his viole da gamba, including the Barak Norman one (London 1697), always hanging on the wall. --
