The BL-4 string Q-tuner bass pickup

Information

The passive BL-4 (Bass Large) Q-tuner for 4 string bass, combines the power of high-performance neodymium magnets with greater efficiency "free standing" air coils.
The BL-4 Q-tuner exhibits clarity, transparency, enhanced low-frequency definition, and above all, an extremely wide dynamic range. Optimized winding geometry to give ideal value/dcr ratios; hence, maximum humbucking action.
Available in High Z (bridge) and Medium Z (neck) versions and they come protected with transparent covers. Check out the gallery for pictures.

Order & customize your Q-tuner(s)

  The shop section of Q-tuner.com will remain closed for a while. If everything proceeds according to plan, we'll reopen next year. In all probability, the current range of products will be replaced by the second generation Q-tuner. The second generation Q-tuner represents a true technical break-through for being the first all passive "smart" pickup. A patent application including a robust claim tree will be filed within a measurable time.  

Because the Q-tuner is partly handmade, the average time between order and delivery is currently about 4 weeks. 22USD for the Shipping, Handling & Insurance each order. We ship wordwide. We offer all our customers a 30-day money back guarantee. Please feel free to contact us with any questions you may have.
