Hi Everyone,

I'm an owner of a Fender Mustang 3 V1 amplifier, and I got to say it's one of the best solid state amplifiers I've ever played. I love to use it. But, due to a big problem in the amplifier, I've been through two of these Mustang 3's (both V1) because of the same problem: The amplifier doesn't receive any signal. I returned my first Mustang 3 to the Fender dealer in my country because the amp just goes dead. All the LED's are on, but when you strum any string, no sound comes out. So it got replaced. I got my second one, and on the first day of playing it, again I encounter this problem.

This only happens when I play for an hour and a half, turn off the amplifier for less than 3 minutes, then turn it on again. No sound comes out. Then for after about 10-15 minutes, usually it's still silent, then you hear a loud pop, then the sound comes back on. This has been very problematic. That's the only problem I encounter. The tones are great, but this problem has been getting to my nerves.

I'm using a Squier Standard Stratocaster (still saving for that 2012 Am. Std. in Maple neck and Oly. White) and I've changed guitars to check if its the Squier's problem, fortunately (or unfortunately) it isn't. Also, I live in the Philippines, if that's worth anything to you (hot temperature on March to Mid-may, oppressive humidity and alot of rainfall from June - mid october)

If anyone has a suggestion to what's happening and what to do, I would be very grateful! :D

Cheers,
Jethro

Hi jethroo

I have seen similar behaviours with other guitar amps. In those cases it got solved using a power conditioner. most audio amps do not react well to power spikes on the line (even subsecond power spikes) and the power supply or power amp termal/overvoltage protection will kick in for some minutes until the circuit cools down.

Thanks for that suggestion! I'll give it a try. My amp is directly plugged into the outlet, so I'll see if using a power conditioner will solve it.

Hi,
yes!
i had that problem with my first solid state combo.. Laney World Series 60... it became muted for some minutes..
no emulation or digital circuits on it , just analogical components..
in the actual Mustang 3 V.2 , in certain moments of the working days , occur some malfunctions with delay effects (i don't have identify exactly if there are other effects involved) .. for example in the Tape Delay the echo repeats suddenly loose their transparency and become muddy as in the Step Filter or in a Phaser sweep..

on the other hand unfortunately, by connecting the amp (and / or the Roland GR55) to the filtered power strip, in my case a common filtered (EMI/RFI filter) power stripTrust from a few Euros, you lose a little 'beauty in the sound .. it seems that it gets a little 'flatter.
The best thing would be to invest some extra cash in a power strip filtered of better quality.
You should find good middle ways without having to go to extremes like the fine BlackNoise filters for example. I'll be boring to repeat it, but I will never regret to have bought one for the components of high fidelity.

Hi jethroo23,

We wanted to chime in here and add our thought that it sounds like there may be some type of power/power quality issue going on here. Since you have had two units behave in the same manner. I would suggest (as other folks posting here have , thanks all) that you try getting a good quality power strip with surge protection and connect with that. Also, you may want to take the amp to a second location to test it on a completely different power circuit to compare. Please let us know how this goes and if we can assist further.

Best Regards,

Hi guys!

Thanks for all the tips. I will be looking into buying a power conditioner/better power strip. A friend of mine recommended an AVR. I don't know anything about using power conditioners/AVRs/things like that so sorry if I sound stupid :oops:

I've used the amps in three different locations... All without power conditioner, plugged straight into the outlet.. The same problem happens, and it happens early as 15-25 minutes after turning on the amp, then turning it off and back on again in less than 3 minutes. Then they live again after 5-10 minutes.

Hi jethroo23,

Based upon the behavior you described, it sounds like it might be a good idea to use a power conditioner to see if helps resolve the issue you are seeing. Please keep us posted. Thanks.

The same thing happens to my Mustang II.

When the amp is cold, like playing it for the first time in the day, the amp will last for like 5 minutes of playing then a pop sound will occur within the speakers. however, the amp is still functioning. it's just the speakers that are popping.

then after turning it off and then on again, the amp will only last for like 30-60 seconds then the speaker will pop again.

then after resting the amp for like an hour, it will last for 4-5 minutes again.

Its warranty expired last june.

I'm also from the Philippines.

I'm using a washburn electric guitar w/ dimarzios and fender cable. I also tried to my stratocaster however, nothing changed.

Here's a video:

OK trying a different guitar was a good idea. I'm kind of surprised nobody else suggested trying a different instrument cable ... it's worth a shot, and could certainly cause the same symptoms.

Hi Guys,

We wanted to chime in here and suggest that a good quality power conditioner may be helpful. If the local electric service is not particularly stable or consistent, you both may be seeing low voltage (brown out) or high voltage (surge) issues. A power conditioner with a voltage regulator may be useful. Please let us know how things are going, and if we can assist further.

Best Regards,

Tried using another guitar cable... The same thing happens.

Tried using a servo powered AVR, the problem still occurs.

an0daw, first of all, nice playing in your video! Really sorry to see what's happening with your amp though. Can you please describe how you have everything connected? It looks like you are simply connected straight from the guitar to the amp with no pedals, correct?

Ohh, thanks for the compliment! :)

Yup I am connected straight to the amp w/o pedals...

Guitar > cable > Amp

Outlet > servo AVR > Fender Mustang II

EDIT:
I tried playing with an earphone on, the problem still occurs...

The sound still goes out after some time then I have to restart the amp to make it working again.

When playing thru speakers, pop sound will occur then no more sound will come out,

While playing thru earphones, there's no pop sound but guitar wont sound anymore...

BUT, if i picked hard on some string, there's a little bit of sound coming out of the earphones. like a hiss but it responds to my picking.

Hi an0daw,

Thanks for your feedback. Are you hearing the same issue on multiple Presets, or mainly on high-gain amp modelling settings? Please let us know and we will be happy to assist further.

It's the same with all other presets...

It happens with clean, high gain or somewhat crunchy...

The popping also occurs with just turning on the amp, after leaving it for like 10 minutes...

The amp will produce a pop sound then after the pop sound, if you tried to play the guitar into the amp, no sound will come out. But the amp's interface is still functioning. even with fuse.
