Re: Decompression technique
If taking the battery out means the output is too low then you'll need to run the uke through an external preamp. You obviously wouldn't have any issues with doing that (and the DI that it would probably need too!). I edited the original post to suggest lowering the pickup which would be my number one solution before taking the battery out.
This is why I hate active bloody instruments! The only active system I've ever liked is my LR Baggs M1 Active that's in my acoustic. No fuss whatsoever.
