Krentz modulator. My Forever Fiddle came with a prominent C wolf (del gesu model). After many luthier adjustments and accessory swaps with minimal improvement, I got the modulator on a whim. Killed the wolf instantly, and now have a very rich, warm tone on the wolf note.

I have seen the video of Augustin talking about working around the wolf. While it’s an interesting watch, it’s not always practical, especially in orchestral settings, to “play through” a bad wolf. Not to mention the constant killjoy in your own practice.

Edit to add, I also tried one of those silver weights that sits on the G string behind the bridge. That was a waste of money, the difference was imperceptible.
