Something a little strange has happened the last couple of times I've changed strings on my Modulus Q6. A couple string changes ago I noticed that the first fret across the bass would have a real thin sound with no sustain...the sound you would get if your action is too low. So I raised the bridge saddles a little across all the strings and it was fine. My last string change the same thing happened but it was happening at the first two frets this time. This time it didn't happen right away though. I did a couple gigs and it was fine..then in the middle of another gig it started happening. Again, on set break I raised the bridge saddles and the sound is now fine. I have never had to do this in my year and a half of owning this bass. I've probably changed the strings nearly a dozen times over that period of time before this started happening. My questions are basically, should I worry about this? Will I have to keep raising the saddles until they can't go anymore? They're pretty high already. What could be causing this, and is there anything I can do to prevent it in the future? Next time, would removing the old strings..lowering the saddles, then putting the new strings on help any? Much thanks.
