While surfing through the usual sites, I found this on the Luthiers Access Group site. Chris Larkin Reacter 5B From Master Luthier Chris Larkin, we offer this fine bass. The body is Brazilian Mahogany, topped by Spalted Beech , with a matching headstock. The neck is also Brazilian Mahogany with a Rock Maple center section. Indian Rosewood fretboard. The pickups are by Kent Armstrong , the preamp is by EBS ( yes, THAT EBS!). The preamp is a 2 band unit, with an enhanced midrange filter. A very useful and unique preamp indeed. Wow! Has anyone tried an EBS onboard preamp?
