Hi, I posted this in the DB forum, thought maybe I'd have some luck in this section. My bass, while not a top of the line bass, is a good instrument. The g string rings out clear and loud all the way up the neck. The e string is loud, clear, lots of great growl. But the d string starts getting dull as i move up the neck, and the a string is even a little worse. It's been set up by a good luthier. I use Spiros, have tried both the Mittels and Weichs with pretty much the same results. Is it just the nature of the instrument or can something be done? I'd appreciate any thought at all, thanks!!!
