Noise when unplugging while tuner is on

Batteries are really cheap, or turn your amp off, or pull the amp end plug out half way.
More on point, my TU3 doesn't do that.

 

You get up to 1500 or so hours out of a battery (this obviously varies, the point is batteries last a long while). The thing to do is make sure you've got backup batteries just in case. You'll save so little battery life by unplugging for 30-45 min over the course of a gig that the juice ain't worth the squeeze. Leave it plugged in, change your battery every 3-4 months as a matter of principle, and carry spares

 

Fresh batteries in the day of the gig, and spares just in case.
Also, check your wiring/power to all your set-up.
Good luck with the gig!

 

Can’t speak for everyone. But I almost always do. I just make sure the cord is off the floor so nobody snags it and knocks the bass over.

 

I leave mine plugged in, never had a problem.

 

Mute your tuner when you unplug. Silent tuning and unplugging is the whole point behind having a mute on your tuner.

 

Unsure if this what the OP was first stating, or not... I can't use lack of coffee as an excuse, this time...

 

"Tuner automatically mutes when the tuner is on."

From Boss TU 3 web page. How are you powering the tuner?

 

If this is true, I would think the tuner is working as expected... have you ever tried the same scenario with a passive bass?

 

Which jack are you using... Output, or Bypass?

Not sure if it would matter or not, but manual does suggest turning instrument down, before disconnecting (with tuner muted).

 

Gotcha... just when disconnecting.

 

If you're not already checking the tuner solo, isolation from the rest of your signal chain might give a clue to the problem, too.

Bass > Tuner > Amp

 

Mogami Silent Plug cables have never let me down.

 

Is the pedal after your tuner plugged into the “OUTPUT” or the “BYPASS” output on the TU3?? That’ what it sounds like is happening.

 

Step one: isolate and test that Tuner. It should not make noise when muted. If it does, get rid of it and replace it. Not worth the hassle of workarounds and long discussions. Just replace and move on.

Step two: Have backup batteries, if it’s a large/important gig then replace the day of. Always test them first because I’ve had bad batteries as well. You should be fine to leave the bass plugged in for hours and not have issue.

I play weekends at church. Well do soundcheck, service run through (entire set) and then 2 services Saturday night, then same process again with 3 services Sunday morning. I’ll leave my bass plugged in from about 2-8 PM, unplug for the night, and then again from 6AM-1PM without unplugging between services. I’ve done multiple weekends without changing batteries. Usually Christmas and Easter are good events to change them, and usually if I change strings or major maintenance then I change them. You really can go 6 months or more on regular use. Luckily, the bass won’t just completely die, but will slowly start to sound more and more distorted and lower volume, so it’s not a set killer if you notice it during a song.
