Double Bass Boomy notes.... any ideas??

I've never heard of the wolf eliminators that go inside the bass... sounds like another fun thing to play arround with!

There is a wolf-tone eliminator that is often used on cellos, and sometimes on basses. It is a tiny weight that is lightly glued through the ff hole to help with wolfs. Quite effective, and reversible if need be. PM Jeff Bollbach; he just used one recently on a customer's instrument.

Changing ff-holes with a rasp is borderline butchery.
 
thanks, Bierbass, I'll PM you in a sec.

just for clarity, maybe a "rasp" isn't what i saw. he used a round file, about as thick as a chop stick. is that a "rasp"?

apologies to all resident luthiers who got heartburn from reading this thread... :smug:

I've also witnessed the filing of f holes by the same luthier as David has mentioned. It was done to my old German bass. Basically the guy grabbed it out of my hands and started filing before I could say a word. It made me sick. Yes, it changed the sound and the strings vibrated more freely and all that, but it doesn't seem to be ever a permanent fix because I've seen instruments that the guy worked on over the course of years, some of them 18th century Italian, and the f holes' shapes were distorted. uuuhhh, Thank you, but NO!

Every time I ever took my bass to the "superman" of bass repair (heh-heh) he'd look at me and "What's your problem?" and proceed to file down the f-holes. As you said, the effects are not long lasting. I wonder if there's half a finger rolling around in a bass somewhere.

A dumb question from someone who is totally ignorant of lutherie. How could a permanent change to the bass not result in a permanent change in the sound? :confused: Does the wood grow back?

What I observed is that the problem this gentleman was trying to fix by filing the f-hole, some vibration or lack there of, never seemed to stay fixed because the next time the instrument was in for an adjustment, more wood got filed off.


That's what I meant to say, but it came out sounding really dumb because of my ignorance.
