Anyone else's GK Legacy make a POP when going in and out of mute status?

Mine does. And it's annoying. Especially in a small/quiet church situation. It happens regardless of the cabs into which it is plugged, Subways or Aguilar SL.

It's not ridiculously loud, but enough to be annoying and noticeable.... about like a light tap on a kick drum, and similar in tone. I didn't try seeing if it was louder or softer depending master volume, because I don't want to have to touch the master every time I want to go on mute... kinda defeats the whole purpose of the switch, imho!

What I'm trying to discern is if this is something normal with the Legacy line (mine is the 800) or if I should send back my brand new amp for another. Thanks in advance for any thoughts or ideas you have to offer!

 

It does it with 2 basses so far, a passive P and an 18v custom LowEnd. If it makes any difference, my volume knob discipline is really good, so this is happening even though I have the volume 100% off/down on the basses.

I haven't tried it unplugged. Will do that Sunday, as I didn't bring the amp home tonight.

 

I don't know about the old Walkabout noises. :-(

This isn't an internal amp "click" or something like that, just to clarify. It is kinda between a "pop" and a "thump", and is amplified artifact sent to the speaker cab. I'm unsure if it's going through the DI. Oo. I should check that with our sound guy first thing Sunday morning.

 

Alright AgedHorse, I tested this a little more Sunday. Makes no difference whether a cord is plugged into the input or not (notice nothing is plugged in for the video shown below) and the volume of the thumping sound is the same regardless of the the gain or master volume settings. This happens no matter what cabs are hooked up, be they Mesa, Aguilar, or Ampeg.

This is really annoying me the more I think about/deal with it. A mute switch should be just that in operation, imho... MUTE! Your TT800 doesn't do this, lol! I LOVE the sound and simplicity of this Legacy, this one thing is just a fly in the ointment to me.



The thing I neglected to check was whether this is happening through the DI out. I recorded this little video before we got to practicing Sunday morning, so the full system wasn't on yet and I couldn't ask our sound-babe (aka: my wife) to verify this for me. I have just not used the mute switch in fear of summoning the dreaded "POP!" heard 'round the world.

Whaddya think? I'm about to call my Sweetwater guys and just ask what he thinks, too.

Edited to tag @rag . Thank you!

 

Thanks wave rider! Hopefully the bat-signal will bring him in!

 

I assume that to be the case, but cannot confirm that and do not have the tools to do so myself. This phenomenon is the same both at my home which was built in 2006 and at our church.

Would the fact that the mute switches on my Tone Hammer 500 and TT800 work perfectly/silently at both locations give any indication of this?

 

Lol! Cute.

But in my situation that is less than ideal as well. With the fast initial taper of the master on this amp (tied with cranking the trim as recommended in the manual) I am BARELY using any master while playing at church, and it is SUPER touchy. Just a whisker of knob movement is the difference between a whisper and a scream here, and what I want is a normal speaking voice.

Sure, I COULD use the master as a mute, but I would inevitably come in way too hot or too soft when it's time to play again.

Using the Trim would be a better, but still less than ideal solution.

 

Oof. Just saw your update, FT. Sorry I pointed it out!

This has me bummed.

 

Hey @rag I just want to let you know I'm not mad or anything, just curious at this point, and would like to know if this is normal operation for the amp.

Heck, I like this Legacy 800 so much I just ordered 2 brand new GK Neo 112 cabs today! I figure I should be a real man and get myself an honest-to-Gallien stack!
