Could have broken a spring in the reverb tank, or a wire connecting it to the amp, or the reverb driver tube, or a few other things, but those are the most likely in this situation. Thats what I'd check first. Give it a little slap and if it vibrates like normal, your spring is probably ok, you can still open it up and double check though. Check your wires. Then pull your reverb driver tube and replace it. If that doesn't work, it is probably in the circuit somewhere, and you should not work on your amp unless you know what you are doing. They store large amounts of electicity in the caps and they can kill you.

Fender Amplifiers are notorious for their reliability issues.However, I'm sure that amp will sound sweet once you get everything working again!

The problem is likely your "tank". The tank contains the springs which create reverb as the guitar's signal is sent through them. A broken spring could be causing your problem.

Luckily, any of the larger music stores should have them avalible.

Good Luck!

Fender GDEC 3... | Answered on Feb 08, 2020


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.

Main thing to verify is that the particular footswitch and cable you have is specifically for that amp. If it is not the right one, that is your problem as there is very little compatibility among footswitches.
Looking at the schematic, plugging in JUST the cable shifts operation as you observed. This uses a crazy circuit in which AC is applied on the cable and the footswitch has a diode each direction that causes the amp to shift between the states. when you plug a bare cable in, it disconnects the internal diodes and switches for control at the amp, hence the signals float.
You should investigate the footswitch to make sure it is the right type with the diodes resistors and caps that is for the Fender Deluxe.

You can find the schematic for the amp here:

http://www.fender.com/support/amp_schematics/pdfs/Hot_Rod_Deluxe_Schematic.pdf

Look at the circuitry of the switches on the schematic at C8. Your pedal should have similar circuitry. Assuming your cable is good, the problem would be in the pedal itself.

In short, you don't! There is no battery in the Fender Strat.

If you are not getting output, you have a failure. FIRST check the cable by using a different cable.

There is internal wiring and the pickups, switches and volume/tone controls that can fail, however the jack is always the first suspect.

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.

modding the reverb takes some electronics experience...if you know where the reverb circuit is. all you can really do is change the input caps that make the tone bright or dull... larger uf for dull... lower cap values for bright... it's in the signal circuits... dont mess with power caps. The schematic shows op amp into the tank and out of the tank to another op amp...Output of the tank to opamp.. Id double that input cap ( 330 pf ) to see if you get more response into the opamp... then look at the circuit C17-C18/R33-R34 894cf4a0-46f7-4f21-9667-be620f05b31d.png

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.

Fender Music | Answered on Sep 27, 2019


Probably a bad transformer? Do you have power on the secondary side? Power in is one thing power out is another, hope this helps?

Fender Frontman... | Answered on Sep 27, 2019


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 . . . .

Here is a test you can do at home for the sound. Test out the speaker. To do this you will need two alligator clips with wire about ft. long. Remove the speaker wire clips under the speaker magnet and attach the alligator clips . Take a C size battery and touch both ends of the battery. You should here a scratching sound . If you do you know your speaker is OK. Then you have a problem that needs a Technician. A good music shop should be able to give you a idea of the repair cost. Don't go to a big music change, find a small full service shop that deals with Fender. I don't think this will cost a lot. Fenders play for years, Its truly worth the bench fee. Good luck DFD , please rate me thanks

Fender Hot Rod... | Answered on Sep 27, 2019


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...

This guitar is from the U.S. Vintage Series
made at the Corona Plant (Fender), USA
in the Year(s): Cannot be determined from serial number,
however you can consult this chart showing the
corelation between serial numbers and dates found on the neck
Fender MIA RI Serial Number vs. Neck Date (Note the earliest I'm seeing is mid 80s)
