Right now Im mulling over the thought of having some work done to my Lakland. I did some searches and didnt really find anything to help me. Basically I live in an area where there are no luthiers (none that Id trust my bass to anyways) and I want to have a side jack hole drilled and a battery compartment installed in my Lakland JO5. Im wanting to get the Audere Deluxe 3 band preamp installed and you have to have a side mount jack, not face mount like the JO has, and I figure while Im having work done on it getting a battery compartment would be nice so you dont have to take the whole plate out to change the battery. Any ideas how much something like this would run too? Id rather not drop 150 bucks just to be able to have the passive tone control along with the 3 band eq, but itd be nice to have if something like this is a quick and easy thing for someone with experience to do.
