I know where the number came from. I've read your posts on JazzGuitar.be and here. My point was Fender themselves don't quote time estimates for fear of missing it, or making people more angry. I hope they do post something in 9 days. Regardless, I had to return mine and will continue to wait for a solution either way.

Just because your particular amp is unaffected proves or rather disproves absolutely nothing. Batches of affected and unaffected amplifiers would have to be examined thoroughly to determine the actual cause. It can still most certainly be the LCD panel.

I did notice something that I'd completely forgotten about on my MII. Whenever it's connected to my laptop, any adjustments I make in Fuse causes digital access noise (for lack of a better description) to be clearly heard from the amp. Any movement in the mouse causes noise. This is typically caused by improper and/or incompatible grounding scheme between two devices. Fortunately I don't have to have the laptop connected to use the MII. LCD panel control circuits may be fully capable of inducing noise so if there is a grounding/shielding issue between it and the rest of the amp, you may get noise.

When I had the MI I had a look inside just out of curiosity. I remember that the power amp section is almost directly underneath the Model selector and effects parameter controls. If the power amp of the MIII is located in the same area, which would make sense for manufacturing reasons, that would put the LCD right on top of or at least very near the power amp module. Remember that power amps are always on at full volume. The actual volume is controlled by how much signal is sent to it by the master volume which is before the power amp. So... cranked power amp and an LCD in close proximity, can certainly be a recipe for noise if the LCD is indeed noisy and poorly shielded and/or grounded.


Wild Guess Department:
Another question I have is what kind light source are they using to backlight the LCD panel? There are still some fluorescent backlit panels out there and they're probably really cheap now. At the price point of these amps it wouldn't be surprising to see them being used. Remember how noisy fluorescents lights can be. Could it be an electronic ballast of some kind making the noise?

Any guesses on how Fender could have looked past this? That's my biggest head-scratcher.

Still in the Wild Guess Department.

Do any of you have a friend nearby who also has a Mustang III but does not have fizz? If so, is there a difference in brightness between the two LCD panels? Is the noisy one brighter or vice versa? This of course pertains to the perhaps completely crazy back lighting theory I had earlier.

I read the Fender rep suggestion to wait two weeks before buying anything else as being as close to a time estimate as one can get without actually using the words, "time estimate". But you are correct in that it was not an official announcement about an impending announcement.

The simplest answer is that they don't actually listen to every amp that goes out the door. My guess is that the product samples they worked with prior to production didn't fizz. Any of the reasonably plausible explanations (not including operator error) that have been proposed here could have come into being at any one or more of several points in production and that could have affected some amps but not others.

I believe that the likelihood that Fender folks heard the fizz and looked the other way is somewhere between zilch and zippo. I don't believe that they are wired (so to speak) that way.

I would have gladly disconnected the LCD but i had to return mine. If a cheap used one shows up i will volunteer to do the test.

Well, if you consider how inexpensive these amps are, it wouldn't be unreasonable to expect that the QC inspections won't be completely thorough. I don't think they're gonna have a guy/gal sitting there with a guitar checking out all the patches and critically listening for fizz. That QC person may not even recognize it if they heard it. That tester doesn't even have to play guitar. They could just be armed with a plug connected to a looped sound source. They may just plug that plug in and ensure that the amp turns on, all the controls work, it changes presets and sound comes out of the speaker. Listening for fizz requires some experience as a guitar player. That means a skilled worker who costs more. Unless it's a fairly high end product, I'm not sure that any amp from any company that is would go through much more than basic testing. This is the price we pay as consumers for ever lower prices.

Personally, I would save my money and buy a better quality product if it did what the Mustang does and sounded as good or better. I don't mind paying more if I know that the quality will be there. Unfortunately, I've heard absolutely nothing that compares to the Mustangs in sound and more importantly, one that equals its control-ability. I've always loved Fender's sound but always wanted more flexibility from their amps. Call me crazy, but I absolutely prefer the sounds I get from the Mustang II to every single amp that I've ever played through. Period. I await the time when some tube snob (I was one) compliments my tone only to have me drop the Solid State Bomb on them. HAH!

I'm 100% on the same level about that.
I was a tube purist as well but the Mustang amps finally got me confinced to use modeling.
And there is absolutely nothing that comes even close and i'm in the business for almost 30 years now and tried every amp known to man.
Forget about line6 that's childplay compared to the Mustang.
The Solid State Bomb is something i'm gonna drop too someday :lol: :lol: :lol:

Yeah. Too bad there's not a way to have a poll on this forum. I'd love to see how many people really would dump their Mustang for a tube amp if they could afford it.

Ha. I bought a Mustang to get away from the buzz and hum of idle tube amps so it was ironic that i got the fizzzzzzzz with the Mustang. I just won a Swart Space Tone Reverb on eBay and look forward to using that for awhile.
