Popping sound when moving amp (?)

My Nashville 112 sometimes makes a popping
sound when I move it while it is turned on.
From reading some of the other posts, I got
the idea that this might be caused by the
reverb unit. Is that actually a spring type?
(I had the idea it was electronic, but I
don't really know.) Is the popping likely
caused by the reverb? (It only happens if the
amp is shaken a bit; careful moving doesn't
do it.) Is that harmful to the amp? Thanks in
advance for any info!

Sounds like the reverb to me. Turn it off before you move it...

Is it sortof "Clangy" sounding when it happens? If so, I'd definitely say it was reverb. Not such a big deal, but at the wrong volume levels, could damage the power amp or Speaker. It's a good idea to turn off the amp before moving it, plugging, or unplugging an instrument. Otherwise, make sure you plug the guitar in first, then plug it into the amp. Unplug from the amp first before doing any other switching of plugs as well. That's probably too much information for you, sorry... too much coffee this morning.

My NV400 emits a crashing noise if I walk by it too close. It's the reverb tank spring bangin'. Turn the amp off before you try to move it or it's gonna make a racket.

Spring reverbs are mechanical, so turning the reverb control completely
counterclockwise when you move the amp would be what I suggest. The Nashville Series of amplifiers have spring reverbs and are not digital.

You know Mike, I always wondered if just turning the reverb gain down would eliminate the crash, just never got around to trying it. Thanks for the confirmation.

And all this time, I thought that popping sound was from a 38 revolver in the hands of someone who hates my playing......JD

Also remember that the power cord on the 112 is able to be disconnected/unplugged from the chassis and can come loose so be sure that it is securely seated as a loose cord can cause all sorts of problems.

It's a lot easier on the amp. all around if you just turn off the volume or Reverb~Knob when moving he amp., rather than turn it OFF and then ON again!
