A while ago I posted that in spite of all the contols on the preamp there was something missing for me. I have been using EMGs practically since they first hit the market and most of my basses have them (and the BTS circuit). So I couldn't help myself. I had to do it. Nobody responded to my post. You guys probably thought that the Sire is perfect as it is and that I'm crazy to do that to this beautiful instrument LOL. But... Apparently I'm not that crazy (or at least I got company now).
My reaction was the same as Anthony Vitty's. "The difference is huge!!!"
Did you wire the EMGs to the stock preamp? If so, did you just clip the ends of the cables EMG provided and solder them to the preamp?
