Charla Posted August 29, 2015 Posted August 29, 2015 Hello Folks I need to replace the pan on my BBNE1. I bought the bass second hand and the pot isn't an original and need help with how to wire the new (yamaha) pot. My mate who is an electrical engineer has done the work, but he seems to think one of the wires from the bridge pickup is missing? So if anyone has a schematic or a photo of the inside of a BBNE1 I'd be very appreciative of a copy? Cheers Charla Quote
ikay Posted August 29, 2015 Posted August 29, 2015 I don't know if this TB link is of any help - [url="http://www.talkbass.com/threads/repairing-preamp-for-yamaha-bbeast.862708/"]http://www.talkbass.com/threads/repairing-preamp-for-yamaha-bbeast.862708/[/url] As well as the pics there's a very basic schematic at the bottom of the thread Quote
Charla Posted August 31, 2015 Author Posted August 31, 2015 ikay I've wired the new balance pot as per the previous replacement and the bridge pickup isn't working. To be honest it looks as if the original red wire from the front PU is missing. Wondered is the wiring for the non original replacement that was in the bass was different? Cheers Charla Quote
ikay Posted August 31, 2015 Posted August 31, 2015 Hi Charla, if you can post a pic of your wiring harness showing the relevant bits I'm sure someone here will be able to help. A missing wire from a pickup should be pretty easy to spot, how do the wires coming from the bridge pup compare with the neck pickup? Quote
Charla Posted September 1, 2015 Author Posted September 1, 2015 I don't have my bass with me as it's with my mate who can solder a lot tidier than I can. But here's a pic with the old pot, which is connected in the same way. I'll get an updated picture when he returns from his holidays! Cheers Charla Quote
ikay Posted September 1, 2015 Posted September 1, 2015 The pups on the BBNE1 look similar to those on my TRB5 (single coil with dummy coil). Each pickup on the TRB has three wires - red & white (hot/cold) and an earth wire. See pic below. The wires on yours may be similar and should be easy to spot if a wire is missing (a bit unlikely as the brown and grey cables in your pic look intact). Quote
Charla Posted September 6, 2015 Author Posted September 6, 2015 ikay Message from my mate to say the red wire from the bridge pickup had a break in it and it's sorted. Just needs me to go and check the out the bass functions as it should? I'll be glad to have it back in action. Thanks again for the help. Cheers Charla Quote
