Hola

tengo un Ampli Mustang IV con su pedal de cuatro botones MS4. Independientemente de si lo conecto antes o después de encender el ampli, el pedal se bloquea y señala en su display el mensaje "U-3".

He probado con otro pedal y sigue el mismo mensaje. Alguien sabe como solucionar eso?

Gracias

Hola String_En Mala Hora,

Parece que el amplificador puede tener un problema de hardware. Regresaré me gustaría confirmar que se va a conectar los pedales a la toma de 4 botones en el panel posterior y no la toma de 2 botones. Entonces podemos ir de allí. Además, ¿qué país se encontró en el?


(Hello String_En Mala Hora,

It sounds like the amp may have a hardware issue. I would like to confirm that you are connecting the pedals to the 4-Button jack on the back panel and not the 2-button jack. Then we can go from there. Also, what country are you located in?)

Thanks for your replay

I bought it at www.thomann.de, but i live in Spain.

I conected the pedal in the 4-button Jack.

(Hi String_En Mala Hora,

Can you please tell me if you have tried to switch cables? Are you using the included cable? Also, you may want to try disconnecting and reconnecting the cable from the amp and/or the MS-4. One last thing, you may want to try simply pressing the buttons on the pedal after powering on, even if it is still saying U3. Please let me know how it goes. Thanks very much.)

¿Puede usted por favor dígame si usted ha tratado de cambiar los cables? ¿Está utilizando el cable incluido? También, usted puede intentar desconectar y reconectar el cable del amplificador y / o el MS-4. Una última cosa, es posible que desee probar simplemente pulsando los botones del pedal después de encender, incluso si aún se está diciendo U3. Por favor, hágamelo saber cómo va. Muchas gracias.

Hi Allan

Yes, i used several cables from the original one it was included with the pedal to another mono cable and last a stereo cable.

I think i have tried allmost all posibilities of conecting the pedal (befor starting the amp, after starting the amp, starting amp with mode-button on pedal pressed. I tried even to reset the amp value to original set.

The pedal doesn't change the sound (i tried it even when it was displaying u-3)

A couple more troubleshooting questions: when you press the footswitch buttons:
- do any of the LEDs on the footswitch change (turn on, turn off)?
- do any of the lights (LEDs, illuminated buttons) on the amp change?
- does anything at all change on the LCD display on the amp?

If you press and hold the left footswitch button for a few seconds, does the amp go into 'tuner' mode?

If you change preset on the amp itself (not using the footswitch), or turn individual effects on/off using the amp buttons, do any of the LEDs on the footswitch change? Does the numeric display on the footswitch change?

It doesn't sound like a footswitch cable problem - the fact that the footswitch gets as far as displaying "U-3" confirms it has a complete power loop. If the answers to all the above questions are 'no' it suggests either that whatever hardware is modulating / demodulating the data signal on top of that power loop is broken, either at the amp or footswitch end. Or that the footswitch is just fundamentally broken.

Either way, it's faulty goods. I don't know what the returns policy is for Thomann between Germany / Spain (it's all EU, so hopefully you're covered), but if it were me, I'd be looking to return or exchange it at this point. Or I wonder if Fender can offer any in-country support in Spain?

Thanks for your help.

None of the led works, whatever i do. The pedal sends no orders to the amp (or the amp is not able to receive this orders.

It's not possible that the pedal is broken, i tried with two completly new footswitches. So the only possibility is a hard- or software probleme on the amp.

The return policy is not bad, there will be no further cost for me to return the amp. But i think that i surely will stay for long time without amplifier, and i planed some gigs with this amp in a few of days.

I'll contact Thomann Germany and listen what they can offer me.

Thanks again for your help

Hi String_En Mala Hora,

Thanks for the updated information. At this point, it sounds like the amp may have a bad foots witch jack or other hardware issue. And it sounds like the music dealer is OK with doing an exchange for you. I would suggest that at this point. Please let us know how it turns out and if we can assist further.
