A hum in the A

rfmichael · #1 03-07-2008, 09:11 AM

I am a new bass player with a relatively new bass. All works wonderfully, but I have a buzz in the high A on the G string. A few weeks ago in removing it from the case, the bridge was bumped and came loose. I have put it back with care and yet the G string seems lower to the fingerboard than all the rest of the strings... and the buzz is worse. I would really like to care for this without major expense, any suggestions?
Thank you!

It sounds like your bridge ended up a little more towards the bass side when you put it back. You can carefully whack it with the heel of your hand to get it back t where it should be. The bridge shouldn't come loose with a little bump, so you might have a more serious problem.

It's hard to tell from just what you wrote, but it sounds like the bridge moved laterally toward the E string side. That would explain the height difference, and the buzz could be from the lower G string action, but it might also be from an uneven spot on the fingerboard at "A". Sounds like you first might need to re-center the bridge...

Carefully whack it?

I actually know what you mean though, try to get the feet aligned with the old marks in the varnish. This may be kind of hard on a relatively new bass, my bass is two and half years old and is still kind of hard to bump the bridge much with out significantly detuning.

yeah, "whacking"

would be gently tapping? i whack my bridge with a paperback when it's tilting toward the fingerboard so it won't fall over.

but rfmichael your bridge should be moved to a precise place (generally that's in the center of the top on the line that runs between the inside notches of the f-holes, so that that line is identical to the line of the top of the bridge). you might be better off putting the bass on a table and loosening the strings so you can carefully move the bridge and check its position.
