1.) There were *never* any BugBasses made with a detachable neck feature. There is a neck tilt function for string action adjustment. The neck should not be removed except by a professional.
2.) The pickup systems used in these instruments have evolved *many* times in the past ten years.
The earliest original BugBasses were passive, and a variety of different piezo elements, different piezo placement, and different bridge designs were used over time.
Several "upgrade" versions were also offered in the early years.
Then there were several different pickup configurations using semi-custom K&K piezos - some only in the bass side "wing slot" of the bridge, some in both sides of the bridge - often including a passive bass boost function.
The most current system is proprietary - involving strategic piezo placement inside the bridge (for optimum tone and volume balance string-to-string), and an onboard 3-band preamp to further enhance the instrument's versatility. This system has been in use for several years, and is now standard equipment on all Azola models.
Just wanted to be sure you had the most up-to-date info.
You may contact us directly if you need further clarification on anything.
Sincerely,
Jill Azola
