Guys I got a problem. I live in KY....and there are NO shops around me that will Install My BQC System in my Warwick Corvette five stringer. Every shop near me that I have went to gives me this line of horsepoopie...it sounds something like this "We cannot install your preamp because your pickups are active and already have a preamp in the back of the pickups" My corvette has Active EMG J set installed I just need a shop that has a QUALIFIED TECH to install this 4 knobs. I don't have to patience to read the wiring diagram and the soldered connections on the back of the diagram confuse me. I want it wired 18v too. I'm getting tired of trying. Looks like my wood chipper might have a new snack soon if no shop will work on it. I have a budget of $80 as well due to the fact that KY lacks decent guitar repair shops.
