Ok, lets get a couple of things straight :)
- Pigs are not sludgy in the least
- The warpig isnt dark
- The warpig is quite smooth and fluid in the highs, and grinding and gritty in the mids.
- Output of the pickup isnt loudness, its how hard it clips the preamp. The magnitude of the signal the pickup makes and the volume you percieve have little to do with one another. A high output pickup will staurate harder.
- Smoother tones are easier to achieve with less preamp distortion, and a high output pickup is more likely to work against you in getting a smooth sound. Rely on the poweramp more than the preamp for smoother tones, drop gain and preamp volume, raise master volume.
And my recommendation - out of all the pickups I've heard, ever, the smoothest is the miracle man. Its also, if only to undermine everything else I said, rather powerfull. But it is bright and sharp, but its smooth and singing with it, not gritty or harsh in the least.
