posted this in an on-going thread and got no reply so maybe I'll achive better results as a stand alone thread: I recently installed the OBP-3 in my Streamer LX 5. it brought out the true sound of the bass but for some reason the output of the bass tremendously decreased to the point I need to crank up the gain and volume on my amp nearly to the max to achive volumes I could reach on the 3 position of the volume knob on my amp with the old MEC 2 band preamp. whats the prob? p.s. I'm running the preamp with a single 9 volter and the pups are MEC actives. TIA.
