But I've noticed that, until now, it only happens when the auxiliar connector is plugged.

Question: If it is just plugged, or is music played over the Aux? What would cause vibration again.
My observation is: Until now I never had a preset change without playing, but sometimes an effect-change.
What couto discribes:

if I change an effect effect mix (exit+rotating knob) it would only take a while before it changes the effect itself- even without playing throuhgh it.

matches exactly my experience on a Mustang 1 and a Mustang 2 !

So there is signal playing through the amp in the form of an aux signal? What is connected to the aux input (ipod, etc.)?

It was easy to falsify my own theorie: It's not a matter of vibrations caused by the speaker.

- Plugged in the headphones and the guitar cable, no USB, no AUX, no footswitch.
- Mod. and Dly/Rev knobs turned to Zero.
- Selected my favorite Deluxe-Preset which has a little bit of SpringReverb Effect
- With pressed Exit-Button I turned the Mod.-control to about 10 o'clock (somewhere near A3 of the modulation-scale) to raise the level of the reverb.
- played 10 seconds with headphones on

= plip! the Phaser-Effect switched to ON. On my MII it is located at -big surprise - A3!

So vibrations of the working speaker cannot be the cause.

I noticed effects seemed to change type on their own when I first got my MII.

Since I find the on-amp adjustments annoyingly complicated (but that's another thread), I only use FUSE to make changes to presets...and I keep the MOD and DLY/REV controls CCW (OFF).

The problem hasn't returned.

See what happens if you turn all the controls to OFF on the amp.


I do the exact same thing, Heyjoe42. I have not had any problems with random effects changes in my MII but every now and then, when I turn it on, it will choose a random preset from the current bank. I really believe that the digital encoders for the reverb, modulation and the preset selector may not be of the best quality. I'd bet that they're also fairly sensitive to static electricity.

Perhaps what you're seeing is due to the fact that the MI and MII don't kill the encoder when powered off. If the unit is off and you turn the knob, a different preset will be loaded when it's powered on.

Interesting, Frente.

So you did turn the knob to the A3 position to raise the reverb volume? It sounds like maybe the knob setting is being transmitted without the knob being turned We'll do some testing here to see if we notice anything on the MI's and MII's we have here. I"ll report back shortly.

Yep, exactly. This gave reason to my presumption that there is a real physical movement of the knobs caused by the vibrations of the speaker and the case. But with headphones connected this is impossible.
I hope the sensitivity or threshold of the selectors are controlled by the firmware, otherwise we will have to live with this...

Until now I experienced the unwanted switching on my M-I and M-II and the M-I of my friend. Not on my Mini so far, which is just some weeks old. And not to forget the unwanted changing of presets while playing! Happens more seldom and I cannot tell you a situation to surely reproduce it.

I'm gonna try to identify under which circumstances the Preset change happens,
but the mod/rev changes happens just like we described before.

Loren,
should contact you through TSL@Fender.com or through another email adress?

That is the best address to reach us for anything Mustang or Fender FUSE related.

For the files:

My Mustang Mini (Ser.No: CMTJ11400866 from DoM 10/2011) does the same, just 10 min ago.

I was playing a Champ-Preset which included a 63-Springreverb as effect. I turned the level of the Reverb down with pressed Exit-Key to a position near A2. After two minutes further playing the Flanger switched to ON without that I touched the amp anymore. The Flanger is located on A2.

I was in the garden, no other electric devices near. Just the guitar plugged in. The was powered via AC-Adapter, not on batteries.

So far all my 3 Mustangs share this glitch, M1, M2, M-Mini.

I hope your technicians can reproduce this behavior.

Greets,

Frente.

This is why I think joebeets' idea in this thread - http://www.fender.com/community/forums/viewtopic.php?f=27&t=69476&p=824092#p824092 - is such a good one. If his idea were implemented, the worst that would happen would be that there would be a sudden change in the amount of effects being used. While far from being a real solution to the problem (I still think it's a bad rotary encoder - as in, cheap), it would at least not be as disruptive as suddenly having the flanger come on.

I think joebeets is absolutely right. The reverb and effects knobs should default to controlling the amount of reverb or effect and not selecting the type of reverb or effect. If you think about it, the way it is now is completely backwards to the way it is on most amps. When you're playing live, the most common changes you'd make, other than gain, volume and eq, would be to the amount of reverb or effect being heard - NOT the effect type. Also, when I'm playing and need to make an adjustment to the amp, I really only have use of one hand as the other one is muting the strings. This is just a case of really bad ergonomics.

Hey Guys,

If you're experiencing similar behavior and haven't sent us an email yet I strongly urge you to do so. Hopefully we can find out why this is happening and what we can do to correct it.

Loren, please read the latter part of my last post as I think a lot of folks who play live would tend to agree. Thanks.

Loren, what more could I tell you in an Email, what I didn't told you here? If your technicians can reproduce this misbehaviour, they should have all the data they need.
The possibility that only my 3 Amp show it is like cracking the jackpot. Three different models bought over a timespan of one year.

1) choose a preset with an effect (f.e. Reverb)
2) change the level of the effect with pressed Exit-key, f.e. to the position about A1
3) play a little bit and wait for the effect change to another (chorus in the factory settings)

Thats all.

I wonder if this problem could be solved with a firmware update.
These rotary encoders are set to detect and respond to the slightest changes in voltage going through the encoder. What if they were reprogrammed to detect a constant voltage change (that would be the user intentionally twisting the knob) and to wait until the voltage matches or exceeds that which was saved in the preset so that you have to twist the knob past the point of where it was in the preset to make any changes? That's the way it works on my GT-8, Behringer V-Amp Pro and the Vox Tonelab ST I used to have. The way the Mustang is now is certainly a bit more convenient than the GT or the Vox's arrangement but they never had this problem and I'm sure that their rotary encoders aren't that much better than the Mustangs'.
