silvertonessuckbutigotone Posted August 6, 2004 Report Share Posted August 6, 2004 this is a variation of the EMG 85 schematic, the EMG has 2 pots, and all i want is 1 pot, would this work? Is there anything I'm doing wrong? I dont know much about electronics and how they work, all i know is how to solder, so any help would be appreciated. oh yes, and im only using one EMG 85 Quote Link to comment Share on other sites More sharing options...
lovekraft Posted August 6, 2004 Report Share Posted August 6, 2004 I hope I'm answering your question - yes, you can run it without the tone pot, no problem. Just leave it out, along with the capacitor. Quote Link to comment Share on other sites More sharing options...
monkey69962000 Posted August 6, 2004 Report Share Posted August 6, 2004 whats up with the 9 volt battery. Quote Link to comment Share on other sites More sharing options...
lovekraft Posted August 6, 2004 Report Share Posted August 6, 2004 The 85 is an active pickup. Quote Link to comment Share on other sites More sharing options...
Saber Posted August 6, 2004 Report Share Posted August 6, 2004 The pickup should have 3 wires: common (or ground or shield), dc supply, output signal. Quote Link to comment Share on other sites More sharing options...
Saber Posted August 6, 2004 Report Share Posted August 6, 2004 And it's hard for us to tell if you have it right since you don't indicate the polarities of the battery wires (+,-), and also since the jack is not drawn in detail. Quote Link to comment Share on other sites More sharing options...

At the base of the pickup wire (the pickup end) it has three wires but aobut a cm away it has a converter that converts it to 2 wires?

lovekraft Posted August 6, 2004 Report Share Posted August 6, 2004 The "single wire" going to the volume pot is shielded cable - if you look really close, you'll see that the shield is soldered to the back of the volume pot. Quote Link to comment Share on other sites More sharing options...

lovekraft Posted August 6, 2004 Report Share Posted August 6, 2004 It's a 2-conductor cable (in this case) in which one conductor is wrapped around the other to "shield" the inner cable from induced noise - the outer conductor, or shield, is usually braided bare wire, while the inner conductor is a stranded insulated wire. You can carefully untangle the shield wire to expose the inner wire, then solder each to its respective spot. Quote Link to comment Share on other sites More sharing options...

lovekraft Posted August 7, 2004 Report Share Posted August 7, 2004 The shield connects to ground, the inner cable connects to the lug on the pot. Quote Link to comment Share on other sites More sharing options...
Saber Posted August 7, 2004 Report Share Posted August 7, 2004 Silvertonessuckbutigotone, it would have been simpler and clearer to just modify the original drawing as such: And just in case you haven't noticed, the black wire between the jack and the volume pot is connected to the pot's body as well as the lug.
