A couple questions on my mv5:

Is there an online manual for the electronics?

One thing I noticed is when I pull the volume knob up, only the pickup pan and volume knobs do anything. I think that is the passive mode.

So is it true when passive is engaged all the tone controls are disabled?


TIA
Yes. You are correct.

Yes, it's passive mode. I use it on stage between sets to save the battery while the bass is plugged in. Also, my MV5 sounds great in passive mode as is, but I do like the active "goodies" you get with the Bart pre and Duncan pick ups.

Read your sig - "All I wanted was a Pepsi, just a Pepsi and she wouldn't give it to me!"

My understanding is that preamps still discharge the battery even when in passive mode. When the jack is plugged in, it activates the circuit, and it is only turned off when unplugged. The active/passive switch bypasses the preamp, but doesn't turn it off. I could be wrong. It has happened before. :)

First, you are correct... the preamp is activated and drawing current ALL the time the bass is plugged in.

BUT, it is also true that when you aren't using the preamp, it's using less power than it would otherwise.

So it depends on how much he thinks he's saving the battery(ies). IMHO, it's not going to be a big enough difference to care about, but technically there is one.

Otherwise, if he simply thinks the battery is not being used when in passive mode, he's simply wrong.

Oh wow, thanks Vic. That makes sense to me. I don't really care about saving the battery power during a 10 minute set break and your explanation seems correct. I unplug all my basses when they are not being used for a long period of time and change the batteries religiously.

I just really love my bass - I played it last night as a matter of fact and it just killed it. Funk - Jazz - Rock - Latin; the bass sounded fantastic and played like buttah. I also echo others' sentiments on the light-weight factor of Mike's basses. I love playing a bass on a 3-4 hour gig that weighs 8 lbs.

Back to the pre-amp and active / passive deal, I wouldn't change any of the electronics on this bass, as it really is "the jazz bass Fender should have made, but didn't" IMO.

Cheers, Pete

You're doing everything right then, so no worries. I'd just say to be kind to the earth, don't swap batteries until you really need to. You can do the math based on the bartolini info, or if you have a 9v circuit, you can also use the batt-o-meter.

For example...

From the Bartolini Web Site:
In 9 volt operation the NTBT-918 uses approximately 750 microamperes of current from 1 - 9 volt battery. This means 1 month of continuous duty or more than 6 months of average usage.

In 18 volt operation the NTBT-918 uses approximately 1000 microamperes of current from 2 - 9 volt batteries. This means more than 3 weeks of continuous duty or more than 4 months of average usage.​
 
The Batt-o-meter is a great little tool!
Yeah, just wish it'd support 18v systems properly. Unfortunately, it's a dead product from a design standpoint. They apparently don't care to revise it at all... just keep them available until they stop selling and call it a day. :(

I took my M5V fretless to a radio show I always play double bass on and the sound man stopped sound check and asked if my bass was dating someone and he wanted to ask my permission if it wasn't. I get the feeling I wont be schlepping the big gun there as much anymore.
