From the EB spec sheet on Bongos:
Single Humbucking with Neodymium magnets*
(3-band EQ: volume, treble, mid, bass)
Optional Dual Humbucking with Neodymium magnets*
(4-band EQ: volume, bridge/neck pickup balance,
low-mid/high-mid, bass, treble)
Optional Humbucking/Single Coil with Neodymium
magnets* (4-band EQ: same as Dual Humbucking)
*Piezo option available on all pickup configurations
(4-band EQ: volume, bridge/neck pickup balance,
magnetic/piezo pan, low-mid/high-mid, bass, treble)
I reckon all of these are available on all the Bongos if you're willing to wait for it.
