Re: Trembucker....
The Blues is one of the best pickups I've ever used. But it's definitely not a hot pickup, it has only slightly more output than a typical PAF-style pickup. If you can get the gain from your amp, it's a great choice. If you need a hot pickup, I'd go with the original trembucker. If I remember correctly, the Parallel Axis Distortion model is one of the hottest pickups Duncan makes, so that might be overkill.
