Boux,did you have the fizz problem with your mustang V? After you re soldered the suspect joints in your mustang V did the fizz go away?

Well, I am afraid I will never know...
It came broken so I had not the opportunity to test it right out of the box.
What I know for sure is that it does not fizzes at all.
I live in a house with no close neighbors so I can play plenty loud. I can't hear any fizz.
Who knows ... could be that fixing the psu with good solder joints all over the pcb silently helped kill the latent/hidden fizz :wink:
While doing some testing with an oscilloscope, either on the send or phones or loudspeaker outputs, I did not see anything special besides some low-level inaudible very high frequency remnants from the power supply, the power amp chip or the digital/analog conversion circuitry. Nothing unexpected or harmful there.
Some spurious signals picked-up by some instrument cables and by single coils guitars can be heard at high gain and volume settings, especially when playing close to a computer screen (I can hear the effect of keyboard and mouse actions when fiddling with Fuse settings).
I own several all-tube amps and all I can say is that the Mustang is generally quiet, with no particularly disturbing hum or hiss.

Just a thought about what fender said about the fizz developing over time,if the problem is with the power supply and maybe fender knows that there are so many power supply's with possible cold solder joints and or other similar circuit board type problems and this would just be too much money for them to fix and also because the solder joints may get worse or even crack and this is why they expect the fizz to develop over time?

So, your amp doesn't fizz (or you don't hear it) and you've never interacted with Fender tech or consumer personnel on the fizz issue. But you feel qualified to express an opinion about what Fender says to those people - that you don't believe what people are being told when they try to resolve the problem as a warranty issue? Even in the case of multiple independent reports? If you have never talked to Fender about this issue, what on earth makes you think you know what Fender is telling them? Others have confirmed the issue. Do you disbelieve all of them?

Yikes.

Since fizz is not apparent on all amps at time of purchase and develops over time (and there seem to be multiple testimonials to that) and since many of these issues develop after a reasonable return period (e.g. 30 days) and since Fender is not, currently, replacing under warranty amps that have, or develop fizz over time, with a fizz-free model, and since (at least in my case) Fender did not offer credit toward an acceptable alternative amp, I think we have a problem.

In my case, this resulted in a real financial loss of around $100, given that the vendor was persuaded by Fender's inability to resolve the issue satisfactorily to accept a return minus shipping both ways. If they had not agreed, I would be out the full price of the amp, and could only recoup my loss by selling an amp on the private market that I would have to disclose has an unrepairable problem, given the number of people posting that their amps don't have that problem. See the problem here?

Let's be clear on one point. I believe that amps that are advertised as having the capability to play clean should play clean. If I buy an amp under the impression that it will play clean and it doesn't, I will take it back. If I wait too long to return it under the return policy of the store, then I will swap it out under warranty until I get one that is fizz free. If the manufacturer can't provide me with a fizz free amp, then I would request credit toward an amp that is acceptable to me.

Hey Boux. If your amp arrived broken, why didn't you replace it?
And yes, amp internals would be interesting! But I wonder if Fender might not like to have these details posted here, so better post in a neutral forum?

bborzell: I see the objective not as persuading Fender to do anything, as the working assumption is that they won't. It is to find the root cause and maybe have the option of fixing it yourself.


In my view, the root cause is the use of components that have either a high failure rate, a wide range of performance outcomes or both. In short, cheap, unreliable and inconsistent electronic parts. There is little doubt in my mind that Fender has many suppliers for the same components and that they have accepted a range of performance specification that allows for some degree of variability in sonic output which just might include the fizz.

I am not confident that amp techs or engineers who don't work for Fender will be any more successful in pinpointing the root cause than the Fender folks have. In fact, were I to lay a bet on the table, I would put my money on Fender having full knowledge that the fizz came from the use of cheap components and that, with the passage of both time as well as the current stock of Mustang amps, the buying public will begin to see Mustangs that are built with better components and goodbye fizz. I just don't believe that they will ever say, "Whoops, we went on the cheap and aren't we sorry".

A competent professional, qualified engineer should have no more difficulty in identifying the problem than a Fender technician. It's not that Fender can't find the cause - it's simply that they don't wish to disclose it (a point I believe you raised in your post) almost certainly for fear of product recall/rectification costs.

I certainly agree that a component issue is a prime suspect, based on current information. But as yet we still have no independence conclusive evidence. If we can get a fizzing amp examined, we may get some answers.

As yet, I'm still awaiting to hear from anyone with a fizzing amp in or near Napa, San Francisco that is agreeable to having their amp examined.

Rich :wink:

Oh snap! My amp started fizzing!

I've been fizz free since I bought my MIII in May 2011. But I've been following this thread with great interest, a little skepticism, and with wishful thinking that the problem is isolated to a few lemons. Well I’m a believer now.

I guess it’s possible that I've always had it and just never noticed it, but I've tried many times to dial in the cleanest setting I could get and listen for the fizz. I never heard a sound like the one I’m hearing now until a few days ago. It’s almost like a phaser effect in the trail of the note. And at this point it is still very subtle. It’s still not a deal breaker for me, I’m mostly a dirty blues and classic rock player. Never the less, I don’t like that it’s there.

So anyways I started to experiment to see if I could find what combination of settings produce the fizz. For my experiment I only used the Fender model amps. I didn’t test the Super Sonic or the other “dirty” amps as it doesn’t seem to be a factor on them. Amp gain on 1, Amp volume on 10, Bass, Middle, and Treble all on 5, Master Volume at a comfortable level.

I found that the 57 Deluxe, 65 Deluxe Reverb, and 57 Twin Reverb models all fizzed.

For the other amp models (Bassman, Champ, Princeton) my ear was not discerning enough to detect any fizz.

I also tried mixing and matching cabinets and turning off cabinets. The Cabs had no effect on the presence of fizz. It was either present with the amp model or not.

Can anyone else confirm that it’s just those three amp models that are effected? Or is it just me?

I hear what you guys are saying about shoddy components, and I’m not ready to rule that out, but I’m also not convinced that it’s not in the DSP.

Well with the thousands of angry customers you shouldn't have any problem finding somebody to part with their unusable fizzing amp !

For what it's worth, I just bought a brand new Mustang 3 a couple hours ago.
Manufactured: 02/20/11
It fizzes like mad.
Not happy....at all. :x

Just curious ... did you know about the fizz problem beforehand?

I read about the fizz, went to my local dealer, tried a Mustang 3, no fizz so I bought it. I have a month to return it so I'm hoping if it's going to fizz, it does it in the first month. Production date 09/20/2011

Wow, that's a new one. I'd love to know if changes have been made to the recent ones?

No. I had a Mustang 1 that vibrated due the small, enclosed case. Decided to trade up and got the Mustang III, noticed the fizzy sound right away, on preset 22. Then I read here a firmware update (1.6.4?) was supposed to have fixed it, updated to 1.8...not fixed. At all.
