Pickups and electronics
The AV Basses instruments are equipped with passive and active electronics.
Passive electronics means simple wiring of pickups to potentiometers of volume and the so called tone control into the output jack. Active electronics means adding a small active preamp between these potentiometers and output jack. It is possible to use an equalizer to control bass, mid and treble frequencies.
As a standard all AV Basses instruments are equipped by AV Basses electronics. The frequency of the active electronics is set to 200-800-5500 Hz. These values can be adjusted according to your needs. Common wiring of the electronics is volume with push/pull potentiometer to switch to passive voicings, blend between pickups or another volume potentiometer, treble EQ control with option of passive tone control in passive voicings on the same potentiometer, mid EQ control with push/pull to switch between 400/800 Hz or parametric EQ mids on stacked potentiometr and bass EQ control. The electronics are powered by 9V or 2x 9V batteries. Instruments with active electronics are always equipped by a stereo output jack that is connected to the negative pole of the battery. When the jack is disconnected from the instrument, the active circuit is interrupted and the battery does not discharge.
AV Basses can also be equipped by electronics from well-known bass guitar equipment producers, such as Bartolini, Aquilar, EMG, Glockenklang, Basslines, Nordstrand and many others. All of these brands offer a large options of wiring. Don't hesitate to ask if you are looking for semething extra.
There are several categories of pickups. You can choose from active or passive, but mainly from singles or humbuckers. Active pickups require a 9V battery (in this case it is not yet active electronics).
Passive pickups can have open pole magnets or can be fully hidden in plastic or wooded covers. Each pickup deserves a more detailed description.
Traditional models AVJ and AVP are equipped by Nordstrand, Aguilar or Lundgren pickups . The modern instruments AV1 and AVS are equipped by Bartolini, EMG, Nordstrand and Aguilar pickups.
