So, I bought a "new to me" 750k. Of course the previous owner said it worked perfectly. Was in pieces when I bought it, why not trust him!? My bad. I set it up, all of the triggers sound like they should but the kick-kp65 and the snare -xp100s. Both of them come in lower volume and sound like they have a "hall effect" very hollow sounding. When I turn them up a bit I get a harsh triggering noise. the snare in particular sounds like it just triggering a snare wire sound, the cross stick trigger is very low volume and doesn't really have much of a wooden click-just a snare wire sound. I have tried moving the cables, using the xp80 pads in place of the 100. I reset the module, I updated the firmware. Is it a bad connection in the module? Any insight would be appreciated.
