Amp sound fuzzy and out of tone.

It does indeed sound like the power amp section. Contact the manufacturers customer service department for the schematic. Then trace it back to the problem. If you do not know how to do this, you're best taking it to a repair shop. If you poke around inside with out knowing what you're doing you can fry something or get a nasty shock.

Hi!
At this point, I would just take it to a tech rather than poke around in it. It sounds like the power section is the problem as you have guessed, but without the technical knowledge you'd be shooting in the dark. That particular amp is right on the line of being expensive enough that would be worth repairing, but you might do just as wel to check Ebay for another used one.
Good Luck!

Tone is a hard thing for some to achieve. Kinda sounds like the amp isn't satisfactory to you as a player. I use an ADA MP-1 with a quadraverb GT and I can sound like Steve Vai with almost any amp. The pedals you mentioned should all sound pretty good with almost any amp. You kinda sound as if your amp sounds wimpy. ALSO, a good metal distortion is a combo of effects as well as tone(layering). The sound you may be expecting may be the sounds of 4 effects combos at a time through a line mixer making it all sound like one sound. I use rack stuff BECAUSE I can get the sounds that NO pedals can give. This also sounds like your knowledge of the equipment needs improvement. True tweaking of gear takes years to perfect, especially if you're a picky guitarist like myself.

There could be several reasons why your Fender 25R amps are not producing the tone you expect. Here are a few things to check:

1. Make sure the tone controls are not bypassed: Some amps have a switch that bypasses the tone controls. Check the manual or look for a switch on the amp to make sure the tone controls are engaged.
2. Check the speaker: If the speaker is damaged or wired incorrectly, it can affect the tone. Try connecting a different speaker to the amp to see if the tone improves.
3. Check the EQ circuit: There could be a problem with the EQ circuit that is preventing the tone controls from working properly. This would require opening up the amp and checking the circuit with a multimeter.
4. Try using different guitars: Different guitars have different tone characteristics, and some may sound better with different settings on the amp. Try using different guitars to see if the tone improves.

If none of these solutions work, you may need to take the amps to a professional technician for further diagnosis and repair.

First, don't open the amplifier! There's no user serviceable parts in it. Second, I think what you mean is that your clean channel is working, but the distortion channel is not. This usually means that there is something broken in that circuit. Take the amp to any guitar store and they will be able to tell you for sure.

If you don't want distortion, get rid of the overdrive pedal... Twangy USUALLY comes from the GUITAR and NOT the amp... test it on a different amp to decide... Buzzing CAN be caused by "fret buzz" which is due to IMPROPER guitar setup such as neck bend and string height.
Start using ONLY clean channel on the amp and NO reverb. If you verify that the guitar sounds bad on a different amp, take it in to have it setup properly.

Hi,

It's not your pickups. It would be nearly impossible to loosen a wire inside of your guitar by having even heavier than your amp head drop on it. It is most likely your volume pot. The post, if hit hard enough, can virtually distroy your pots. Another possibility could be your jack, al though considering where it's located on your guitar, it would be very hard to damage it by having something drop onto it.

There is little else that could be the problem. Hopefully you didn't damage your guitar too badly. If the guitar was in front of me, it would be a relatively easy diagnosis.

Fortunately, volume and tone pots are inexpensive, and if you're handy with a soldering iron (or you have a friend that is) it is an easy install with four to six solder points, depending on your configuration. I don't want to assume it's a stock setup, but when you take off the rear electronics cover, you will immediately see what configuration you have.

If you have possibly damaged the pickup bobbins (assuming you have the stock humbuckers in your guitar), you would be able to see the damage, It would either look damaged,or work correctly. As you know bobbuns are simply wound wire, and that's not easy to damage. Plus your strings provide a minimal amount of protection, unless your amp head slammed it very hard. Start by replacing the volume pot. Cheapest parts first. There is no way to test the pot with anything like a potentiometer, because there is virtually no voltage that passes through the pot. Additionally, unless you have active pickups, your pickups cannot be either. If you do have to replace your electronics, you can find a large variety and even upgrade your parts by searching eBay. The good thing is that you havce a guitar, and guitar parts are abundant, relatively cheap, and most people change out electronics just to achieve a different sound.

If you are so inclined, most good guitar shops will diagnose your problem for cheap and apply the cost of the diagnosis to the cost of the repair. Good luck, and I hope I have given you some information to work with.

Personally, I like to have all "tone effects", such as wahs, distortions and equalizers in front of "time effects" such as phasers, chorus, flangers and delays. See my set up in the photo. Guitar input is from right to left, starting with the wah pedal.

I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.
