Unusual problem
« on: February 15, 2010, 09:06:11 PM »
At my last practice I was playing the Englehardt upright when I noticed something a bit...odd.  Everytime I hit a G-note, it sounded dead and half-volume.  All the G's in every position on the neck had this problem.  Every other note sounded loud, proud, and perfect.

Anyone ever had this happen before?  I changed the batteries in the preamp which seemed to help, but not much.

It sounds like you have a wolf.  Wolf notes are common in the G-B range.  Have you changed strings lately?  It could also be that your soundpost moved.  Are you able to keep a constant humidity or is it changing a lot?

I have one at e flat---sixth position on the a string on my Pace---it drives me nuts, and it's right in the middle of the playing field.

Strings are Weedwackers, don't know how much they're affected by humidity.

Soundpost may have moved, I'll have to check.

It stays in the practice site which is climate controlled (unless I take it to a gig).

I looked up wolf note since I was unfamiliar with the term and it doesn't really sound like that's the problem.  It just sounds like I've turned down the volume on all G notes.  There's no change in pitch.   ???

In it's worst apearance it's a wolf note...In better situations its what we call a dead spot on an electric.  Sorta the place where the resonant frequency of the bass and the note are the same.

I'm looking forward to hearing what is making this happen. I've been stuck with the reverse of this situation, where you will get a frequency specific rattle or vibration in an amp. That can be a pain  too, but I've never had an acoustic instrument that had a dead note, that was dead at every position.
Sorry I have no input for you, but I'm dying to hear the answer to this one.
