Passive playing

Actually, if you compare the sounds, even with the bass EQ on flat, it still produces a different tone. I always thought playing in passive is a good thing, because you arent using the battery.

The battery is engaged as soon as you plug the bass in. If the Volume DID released the battery, then you would hear a loud POP using the Volume switch from passive to active. It is the cable plugging into the Jack that activates the battery so it is always being drained, even if you cut the cord off and just put in an un-wired plug in there!

Passive playing has zero bleed thru from the circuit even if set all flat. The sound is probably 99% or so the same set flat but in passive, it is 100% by-passed.

Playing all passive is fine, forever with no problems if that's what you like. IF you wanna go only passive and never use the circuit, then take the batteries OUT of the bass. Then, pushing down the volume knob will be the same as an on-off stand-by switch.

The difference you're hearing is probably just the preamp gain. You can adjust it to match passive to active (with all controls set flat) with a mini screwdriver.
On the older 9V version look for a little blue plastic cube on the Mid control board. On the newer 18V version it's even tinier, white color, on the main middle board.
If set properly you will not hear a difference.

As always, I could be wrong

All basses shipped new from here have the volume matched between the passive and active modes without any gain added. If it is different between active and passive modes when set flat, it was changed after we shipped the bass.

I like using the passive mode sometimes because it makes me appreciate the active that much more when I push that knob back down

I'm with you in that. After a while, I get unsed to the passive sound, then when I'm in the mood for a boost, I press it back down.

I guess that goes without saying...

By "properly" I meant the proper way to match volumes.
If one wants some gain boost when preamp engaged that's what it's there for.
No absolute proper way...

I think what Ken is trying to say is that after it leaves his hands, someone else altered (tampered) with the factory settings. In other words, don't blame KSB if it's not as Ken described.

I totally understand what Ken said. I wasn't blaming anyone for anything.
I was trying to say that it is most likely that the basses go out of the factory the way Ken described - therefore it goes without saying.
Please read all posts again. Maybe it's my bad English or maybe you just didn't get it right.
Peace.

Passive tone = most all the gig (love the fat passsive tone of my smith)
Active tone = Chorus or slap time just for the pure boost you get when you engage the preamp
