    hello,
    I´ve read abot the wolf terminator and it seems to work. what about the krentz modulator, has anyone tried it? I am curious if this works in a way that the wolf is really gone and not shifted to another note like the weights you put on the afterlength did for me.
    the krentz with the magnet and the black circle vs. the whole machinery on the terminator seems more easy to use and visually less obtrusive.

    my bass has a bad wolf on Ab - A string bad bad warbling, A harmonic as well and doesnt respond well, on the D string the same area is not responding well with the bow and has a mumbling sound, pizz less sustain, low Ab on E string not responding well, much louder than other notes.. you get the idea.
    maybe I need a post adjustment?

    thanks.

    There are a number of ways to tackle a wolf tone, including the two options you've listed. The first thing I try, after the checking the setup of an instrument, is one of those brass weights you put on the afterlength. When tuned and adjusted, they can make a lot of basses work better. If that doesn't work out, then you might consider one of the devices you've mentioned. I have both and have had far better success with the Wolf Terminator. It really does work. With the Krentz, I feel like I'm reducing the bass's output before it starts to help with the wolf. It's possible I haven't found the sweet spot with it.

    ok thanks for the info! I will have a qualified person look at the soundpost first and see where I go from there.

    Sorry to reopen an old thread, but have people had success with Krentz modifiers? I have a semi-playable wolf on my octave G that hurts soloing, but a metallic wolf eliminator kills the resonance and sound I love from my bass

    The Wolf Terminator works for me.

    I like the idea of playing around with the string afterlength or using small fishing weights. I had an Ab wolf that went away when I added a bow quiver.
     
  9. Sorry for the dual post, I originally replied to a discussion in my search results which I later realised is in the 'orchestral technique' forum....
    Both open and/or fingered A natural notes are taking off like crazy on my bass when amplified. This is my first experience of a wolf note, after fitting fresh strings to my 'new' bass. I got a brass lupX, it seems to mute across the board. From my reading, I would prefer the tunable Wolf Terminator over a Krentz unless someone can confirm that the Krentz predominantly affects only the wolf frequency. Unfortunately, WT will not ship to Australia...

    It seems odd that WT wouldn't ship to Australia. Were you told this specifically by the seller (Hideo Kamamoto)?
     
  11. the computer 'said no' at the WT site cart checkout (once I put my address in). I have left a message, in the hope it is just a matter of adding postage to the price... now July 4 is over, I hope to hear back from them.
     
  12. Mr Kamimoto has emailed me, and is happy to post to Aus. He was surprised that the form prevented me from submitting an order and said he will look into it.
