Resurrection ………. Anyway, with the Barcus Berry 3000A pre-amp adjusted correctly,, is sounds pretty good…………… driving a tube Fender Bassman. Only complaints are the super rugged thick metal pre-amps case makes it a bit heavy, but you will never damage it. Also, and this is really more important, you have to remove 4 very small Phillips flat head screws to open the case and change the 9V battery. On the plus side, everything needed to mount the 3000A pre-amp on the tailpiece was included: A Velcro strap and adhesion backed Velcro , plus rubber feet for it if so sit somewhere should you opt to not mount it on the bass itself. Thus the installation, with the clip on type bridge Piezo pickup, is non-evasive and requires zero modification to the bass. It not easy to reach the pre-amp control shafts, so a small flat head screwdriver works for that. The 1/4 inch instrument cable or your WiFi dongle plugs in to the pre-amp,
