Fender Acoustasonic Junior Dsp Combo Amplifier with Effects - Answered Questions & Fixed issues


noise problem with fender jr accoustatics is the poor aluminum sheet ground design that wraps around the body of the amp. it happens to me all the time because i kept on moving/carrying/dropping the amp every time we do church service. i am thinking of using an aluminum cable to wrap around outside the body.

I would try using another speaker to see if you can get the sound back, this will help you narrow down the problem, you can also use the effect send to feed anothe amp to see if you get the sound OK.
It can be blown speaker or output stages,

This probably an impedance problem. Do you have the manual. If not see if you can get it on line. You can then research the impedance of the input and see if you have a problem. Fender website in support area. Hope that helps. Let me know..

Are you asking for the circuit diagram or the user manual?

I'm an engineer, not a musician. The device is a frequency meter set up to display the musical note input to it. If you pluck a C flat and it shows an A you need to tune your instrument till it shows a C flat. You will have to refer to the manual for operation and modes.

yes check the fuse . there is generally a fuse for power switch and that sounds like what your having trouble with. hope that helps you out.

Does it still have a hum/buzz when NOTHING is plugged into the INPUT? If so, you MAY have a tub going bad. If the noise is only there when you have your guitar/effects, etc. plugged in, then the problem is the guitar grounding or effects faulty...
FIRST: When the amp is "cool", UNPLUG THE AMP POWER CORD FROM THE WALL! ! ! ! Then CAREFULLY remove and reseat the tubes one at a time. Be sure to insert back into the socket correctly. You MAY just have a bit of corrosion on the tube "pins"....

SECOND:Don't plug anything into the amp, turn on and warm up. GENTLY tap one tube at a time with a WOODEN pencil. DO NOT USE anything metallic (like a screwdriver....) and be VERY gentle. If the noise increases or decreases, you probably have a tube going bad...

That's all I have. If this doesn't cure the issue, best take it to a repair shop . . . .

While it is possible (probable) it is caused by the AC mains modulating the output due to a power supply fault, it could be caused by inadvertently creating a hum loop due to poor grounding - check out the link below...

You have to get the volume pot cleaned and lubricated. If not a quick replacement should do.

You could buy a Lehle switch, or simply use one on each separately. If you are using a multieffect unit you could make a Y cable to take the output to both amps but that will not allow you to select the drive channel - you still need the Fender footswitch for that, one for each amp. Lehle is a German company and they make a lot of different footswitch combinations but you will pay for the convenience.


I recommend the Fender single button footswitch for this use - Type: Footswitch
  • Number of Footswitch Buttons: 1
  • Manufacturer Part Number: 0994052000
  • It's about $35.00 each, compared to the Lehle which starts at $200. Just put the two side by side and make a metal bar to attach to the two switches - then you have a single bar to activate both drive channels at the same time. I recommend using aluminum bar stock with holes drilled into it for the switches, or find a C channel aluminum bar that will put the footswitch buttons in the channel. You can also make it one inch overhang past both switch bodies and then use bolts to keep the bar in place. If I was doing this I would mount the footswitches on a board and secure the bar to be on top of the footswitches, using coil springs to maintain the bar's alignment vertically at the end bolts.

    Google (fender)(AX-12)(manual) without parens.

    It should be possible. In any case, the reverb spring assembly can be removed carefully and unplugged (should have RCA plugs). When mounting the casters, make sure the fasteners don't conflict/block the reverb mountings.
