Recently I've bought a matched pair on the new Q-tuner q2.0 pickups for my electric 5 string bass. The first thing I noticed was the tremendous output these pickups produce. That's probably because they're being powered by neodymium, the world's strongest magnets. The sound these pickups produce is very clean and articulate, lifelike so to speak. Harmonics ring through like a bell. Killer dynamic response and yet passive. Compared to the transparent look of the earlier Q-tuner, the black q2.0 lost its appeal completely. From a performance point of view, however, there is no better pickup. Summarized: poweful, dynamic and a very broad frequency range.
