20 Most Recent Fender G-DEC Junior Modeling Guitar Amplifier Questions & Answers


Try changing out the Pico fuse. Only 50cents from online West Florida Components. Buy a few. Mine went out twice. It is Item # F021. It is a .5amp (500 mA)fuse-green and looks like a resistor. Location on the circuit board is near the transformer and on back edge or board behind the 2 brown wires connecting to the board and to the side of the 4 diodes there. I left the bad fuse in place and soldered the new fuse to it's legs-a lot easier and does not damage the PCB.

Could be power supply failure

Hi.

If the amp is working, then most of the time the buzz is given by a bad grounding. Test the amp using different wall sockets, and possibly test it in a different home (there may be an earthing problem with the home network). If the problem goes away, then it was the wall socket or the home power network. If the buzzing is still there the problem is with the amp. Check the earth connection at power cord and psu and test the amplifier's PSU components. Check also the audio connections inside the amp (the back of the female jack input sockets). A small contact in there will result in a loud buzz.

This amp uses a TDA2050 chip that has thermal protection. It is also a small amp that is NOT capable of high sound levels. If *********** can't stand to be within 5 feet of this amp you are playing TOO LOUD for this amp and it will shut down until cooled off to protect the amplifier chip. This amp is intended for practice. It would be adequate for sensible listening level in a 10 foot by 10 foot room. If you need more sound you will have to get a bigger amp. I would suggest you get a sound meter and verify the sound level. DO NOT exceed 4 hours at 90 DB... I know a lot of deaf musicians that have lost their hearing and they are not much good anymore.

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.
