I have had problems with the active electronics in my basses dying unexpectedly due to low battery.
I love my Lakland 5501 bass but it died at practice last night. I know that by pulling up on the volume know the bass goes into passive mode. What I did not know is that you need a fully charged battery to do that! If you ask me, this kind of defeats the whole purpose active/passive switch.
So what active electronic basses have true bypass?
The way to test it is to remove the battery completely and see if you can still get a signal.
PS I read that Duff McKagan used to play a Power Jazz Bass Special until one night the battery died right before the big opening chord of the first song!
Sorry you had to find out the hard way. The MK-1 preamp in the 01 series does not have a passive mode. It's well documented. What happens when you pull the switch is that it only bypasses the EQ, but it is still active. If your battery dies, you are bassless.
That and the hideous hissing are the reasons why the first thing most people do when they buy a 01 is to swap the preamp. The most common choice is the Bart 5.2 AP (as mentioned),
