This is the five knob preamp I had installed in my Lakland 55-01. It is the US made Bartolini pre that is three band eq with volume and blend. It does NOT have the push/pull active/passive. It can be run at 9 or 18v. I only ran it at 9v and am including just the one battery clip (which needs attached as I had this attached to my Lakland which has a battery compartment. Looking for $95 shipped to the CONUS.
