[Thunderbird Pro Wiring Diagram]

Hello again, Folks.

Hey, I'd really really appreciate your help on this....I want to purchase a replacement premap module for this bass.  I called Epiphone directly and they told me that I'd have to go to a dealer and have them order it.  I went to (large) dealer and they tell me that their Gibson/Epiphone support person is not responding to the inquiry....multiple tries over 3 weeks.

I'm at a loss on this....how can I get a replacement preamp?  

Thanks in advance for any support you can provide.....really.

What I meant to say is that the pickups are passive and they run through the module.  No option for passive/active.

Hello folks,

 

 I’m working on one of these basses for a friend. It is the full active model. 
 

When I plug the output cable in, sound comes out of the bass for about 2 seconds and then fades off to nothing rather quickly. The battery is minty fresh. 
 

Anyone have any tips on solving this?  I thinking of verifying all the wiring is per the diagram in this thread, and then maybe replacing the module if I don’t find any discrepancies. 
 

Thoughts?

 

 Thanks.
