I have a 2010 Gibson SG Special. I like it, but the pickups aren't winning me over. They get a bit muddy and undefined when I add gain. I tend to add a lot of gain and play heavy rock bordering on metal. I'm looking for pickups that can handle gain but stay defined. I'm not looking to go the active route. So what are my best options? Please keep in mind I'm in South Korea so many boutique brands may be impossible for me to purchase. Thanks.
