I have a Les Paul with Burstbucker pickups. They sound amazing because they are so hot (very high output). However, when I play with a lot of overdrive, it will constantly squeal (super annoying high pitch feedback) any time I stop strumming or muting the strings.
I added a noise suppressor (Boss NS-2) to the front of my effects chain, which works great for when I'm not playing. But when I'm palm muting the squeal is heard between each strum. How can I prevent this? And no, turning down the volume or reducing overdrive is not an option; this is my metal guitar :).
Maybe tweak the noise suppressor, add compression, noise gate, eq with high end cut out, etc?
