BURSTBUCKER PRO: Tons of output. Very bright. They actually overdrive my Valvetronix amp at its highest gain settings. They are VERY sensitive to volume and tone knobs. You can really change the sound significantly. Even more so than the 57 classics and 498 in my SG. At half volume they have the warmth of my SG's neck pickup, and full volume way more harmonics and sustain almost too much. Pinch harmonics are HUGE in both bridge and neck positions. The neck has more pinch harmonic sustain than anything I've ever used, even more than EMGs just not as quiet. They are however, much quieter than the pickups in my other gibsons. Particularly if you turn down the volume just slightly - hum goes away, without any noticable loss of sound. They are VERY VERY sensitive to distance from the strings. I'm still playing with this. But it effects tone significantly, not just volume. They sound warmer to me farther away, tons more bitty up close. This may all be elementary to all of you, but I've only become interested and skilled enough in the last 6 months to notice such things!
