MuddBass Posted January 7, 2022 Share Posted January 7, 2022 (edited) Hi All, Any Schack pre-amp users here who can help? Before I take this Sei to the Gallery (quite a trek for me), I was wondering if anyone can help with this loose grey wire. I can't see to see where it's popped off from, and everything 'seems' to be working ok, but I don't want to leave it loose. Can anybody compare their Schack wiring with mine or help at all? Thanks in Advance, Greg Edited January 7, 2022 by MuddBass Quote Link to comment Share on other sites More sharing options...
John Cribbin Posted January 8, 2022 Share Posted January 8, 2022 Why not send the photos to Schack and ask them where it's come loose from? Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted January 8, 2022 Share Posted January 8, 2022 I have a Schack bass wih the preamp removed (bass now passive), I'll dig it out and see if it is the same. 1 Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted January 8, 2022 Share Posted January 8, 2022 One of my wires is snipped as well! Can you count across and see if it is the same? Quote Link to comment Share on other sites More sharing options...

Is that to be wire 6 from the volume pot side? Quote Link to comment Share on other sites More sharing options...
Hellzero Posted January 8, 2022 Share Posted January 8, 2022 I have the complete wiring schematic on my PC. Just have to turn it on and you'll get it. Just wait a few minutes. 😉 1 Quote Link to comment Share on other sites More sharing options...
Hellzero Posted January 8, 2022 Share Posted January 8, 2022 Here it is. @MuddBass : your loose grey wire (beware, there's a second one) is the ground, check the wiring schematic below. @warwickhunt : Follow the wires on the schematic below to find where it's going as you have a version with all grey wires. I even translated in English back in the day. And here in PDF too for better resolution : BC3P_Anleitung-1.pdf 1 1 Quote Link to comment Share on other sites More sharing options...

MuddBass Posted January 8, 2022 Author Share Posted January 8, 2022 Looks like Grey 13 so that by the looks of it is used to bypass the EQ if a switch is provided. Perhaps that's why it's loose as no EQ bypass option fitted. Quote Link to comment Share on other sites More sharing options...
