Preamps that are true bypass?
Maybe I am not using the correct words "true bypass". You techies please correct me if I am wrong.
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!
Very surprisingly, MusicMan basses work without batteries, although the signal you get is very low.
Active/passive switching is usually done independent of the preamp. The only time it's not possible is when the preamp has multiple inputs, thus requiring complex switching to wire in a passive configuration; or when the preamp has PCB mount components that make it difficult to modify any wiring.
I have a Stingray with a bypass switch fitted, it's just as loud in either position.
Edit: Oh, you mean a standard Stingray without battery at all? I never tried that!
I have a 55-01 which I replaced the stock pre with a US Bartolini 5.2AP preamp which is true bypass. If the battery dies, just pull up on the volume knob and you're back in business!
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),
Just a note. I bought my preamp from www.bestbassgear.com.
Thanks guys for the suggestions.
So back to my original question:
I think that the following basses have true bypass:
Is this correct?
