I've noticed the switch noise as well, while recording anyways. It's noticeable, but not offensive. I just did a YouTube demo of it. Not sure if this is helpful to anyone, but here it is, warts and all!
It's the boost/comp button, on the far right. You've probably figured that out by now though lol! Tuner is accurate enough, too. Here's a YouTube demo I just did for the Dapper. Switch clicks and all!
Hey there Lync, I've been having the same problem with mine, which is about 4-5 years old. Have you found cleaning the ribbon connectors to fix the problem? Even if only temporarily? And how would one go about doing this themselves?
I've had mine for almost a year and I love it. Great frets, great everything. I gig it stock except for the addition of straplocks. Lightweight too! No one believes it's not a Fender, even other bassists!
