My LB-76 fretless was having some MAJOR neck issues - one piece maple neck, serious problems. buzzing out across all strings below the third fret (well, where the third fret would be). Neck was bowing there and I had been compensating by raising the action, but it was unplayable, so I took it to my local luthier who had it for six weeks. I don't know what he did, but the thing plays like a dream now. Better than ever. AWESOME!!!
