Using a Gretsch 'Tron in the neck position. It's a modern new 'Tron. I like it when adjusted up close, but when it's adjusted close to the strings I find the string hitting the pole screws "popping". When I back off, it's a bit too muddy or indistinct. I'm going to try screwing the pole screws down all the way, but really they aren't up much anyway. Do I just need to go to a hotter 'Tron or a TV J model so I can back off and to resolve this? The heads on the screws are pretty big, was thinking maybe I should buy some steel allen screws and replace them... might solve it.
