i,ll just add this youtube link for those whohave not heard Edicson Ruiz videos on youtube with his 1750 cornerless Landolfi. Btw he uses 3 diffrent bridges, one for 3 string Bottessini stuff, another for low action vieneese tuning and another one with higher action for modern playing. I had a chance to hear this bass for a whole week when Edicson came to solo with our orchestra. Its a dark sounding instrument, that projects really well at far.
