Lastly, make sure the connection between your guitar and amplifier is not loose. If it doesn’t fix the issue, then you need to get a new instrumental cord. Luckily, you can get the Fender instrument cable.

Problem 5: Fender Supersonic 22 Hissing Issue

Some fender supersonic 22 users might face this problem. A loud hissing sound comes out of the amplifier. This may not be an issue while playing on loud volumes. But in the case of home practice volumes, this can be a nuisance.

This happens because Fender usually biases these things toward the colder side. This tends to create a hissing sound. Also, there might be a problem with the build quality.

Let’s have a look at the solutions.

Solution

First, you need to change the bias. Adjust the bias to the warmer side. This will eliminate most of the hissing. There might be an insignificant hissing sound which should not be a problem.

If there is a problem with the build quality, you should claim the warranty. Fender warranty covers the noise fix of the Supersonic 22. 

Problem 6: Fender Supersonic 22 Noise

Nothing can be more annoying than a noisy amplifier. The Fender Supersonic 22 is notorious for its noise.

While switching from the clean (“vintage”) channel to the lead (“burn”) channel, it pops very loudly. This can be very annoying during practices and live performances. 

However, the solutions to the problem are very straightforward. Let’s have a look at them.

Solution

The SS22’s popping issue can be fixed by swapping out K1. Do this if you are comfortable fiddling with an amplifier’s internals. It’s not too hard to do. Otherwise, you will need to take the amplifier to a service center.

You can also use Deoxit contact clear or similar cleaning material. Spray the pins with the tube and gently work them in and out a few times. It might be as simple as cleaning the pins.

Problem 7: Fender Supersonic 22 Reverb Hum

Humming and distortion are sometimes mistaken for one another. However, they are completely different phenomena.

Jammers who have been distracted by a hum during a session find it extremely distracting.

However, the solution is not annoying like the problem itself. Let’s see the fix.

Solution

The good news is that you may eliminate the buzzing immediately. You can connect the audio source system and amp to a single electrical power connection.

Also, try resoldering the connections to be safe.

Keep in mind that you’ll need to trace the source of the humming sound. Do this if it doesn’t work. 

If the humming persists, it would be a good idea to check for loose connections. You need to check the frayed wires in your amplifier too.

Problem 8: Fender Supersonic 22 Reverb Not Working

In terms of surround sound and reverb, Fender Supersonic 22 is unrivaled. However, there are instances when the machinery acts up and the reverb may not work properly.

You might get annoyed and confused with the problem. However, the problem is easily manageable. The solution does not require any special fix.

Solution

A common reason for this is improper alignment. Check if the speakers are properly aligned or not.

If you have access to a similar amplifier, you can hook up the tank. Then you can determine whether or not the amp is malfunctioning. If you connect a different tank and power returns, you’ll know the tank was faulty.

If the amp doesn’t produce a splash when shaken, you can replace the reverb recovery tube. Replace it with the one you know will work. You can test if a reverb has been added by playing through it if this occurs.

If there is no reverb after a splash through the speaker, replace the reverb driver tube. You might require a plan or diagram to figure out which tubes are the drivers. Also, find out which are the recoveries.

4 Fender Supersonic 60 Problems and Their Solutions

The Fender Supersonic 60 is a high-powered 60-watt amp. It comes with tons of great features to improve your playing. It provides a wide variety of inputs and improves your signals without altering their tonal quality.

The question then becomes, “Why the Supersonic 60 guitar amp won’t power up?”

The power chord may tear or break down due to physical damage. Even a blown-out fuse might cause all the hassle.

Whatever the problems are, the solutions are not complicated at all. 

Solution

It’s best to check the power cable on your amplifier first, as it’s usually the source of the problem. If that’s the case, you might want to think about getting a new one.

A professional should be consulted if the issue persists. They will take a look at its individual parts and diagnose the source of the issue.

Fuse protection is standard in guitar amplifiers. In the event of an overload, the fuse will immediately blow. A Fender Supersonic 60 guitar amp may refuse to power on at that time.

There’s an easy solution to this issue. Changing out the blown fuse will get your Fender Supersonic 60 guitar amp back up. 

If you need to replace a fuse, be sure to get one with the appropriate amperage.

Problem 4: Fender Supersonic 60 Overheating

Fender Supersonic 60 overheating is a very common issue among musicians and gigs. This is the direct result of overuse. This happens when you use your Fender Supersonic 60 for an extended time without any break. 

This phenomenon affects the amplifier components and lowers the volume output. It results in low volume output and performance.

Solution

The best solution for this problem is to give the amplifier enough rest before using it again. Giving it enough time to cool down will lower the temperature.

Also, make sure your amplifier has good ventilation. You might want to install additional cooling fans if needed.

Are Fender Supersonics Good Amp?

Yes, Fender Supersonic amps are excellent quality amplifiers. It is well known for its custom reverb effects and clean sound tone. The secondary burn channel has good gain options.

However, we will be comparing it with the Hot Rod Deluxe, Prosonic, and Twin Reverb models. This will give us a clear idea if the Supersonic amplifiers are good or not. 

Fender Supersonic vs Hot Rod Deluxe

The Fender Supersonic series just dwarfs the Hot Rod Deluxes. Overall, the Supersonics are way more superior than the latter one. 

For example, the reverb and echo features are more lively than hot rods. The only upside of the hot rods is that they are louder than the supersonics.

But when it comes to clean channel, OD channel, or reverb, it is out-shunned by the Supersonics.

For example, the SS60 has the best raw blue tones in the market. The distortion of the hot rods is fizzy and medium gains are not up to the mark.

Hence, the Supersonics are better than Hot Rod Deluxes.

Fender Supersonic vs Prosonic

The Supersonic vs Prosonic is a popular debate. Both are good amplifiers and provide excellent sound quality.

However, which one is the best has no clear answer. Public opinion varies from person to person. Some say that the Supersonics sound dull and lifeless. Others say the Prosonics have a fuzzy reverb and mid-gain.

Others say that the Prosonic beats the Supersonic by a large margin. It is not as compressed as the Supersonic amps and provides excellent sound clarity. 

It is also more versatile than the Supersonic. The amp’s “class” can be adjusted using the power supply’s three different settings. It also features a great clean mode and an overdrive.

Fender Supersonic vs Twin Reverb

The Twin is the way to go if you value cleanliness. If you’re looking for pristine tones, look no farther than the Twin. There’s a glimmering sheen to it, a lushness to it, and most importantly, it’s LOUD! 

And the overdrive isn’t half bad, either. The Super-Sonic is best used for more powerful applications. The high-gain path may provide more value in the long run. 

Super-clean Sonic’s channel can be toggled between Bassman and Deluxe settings.

However, weight is a factor between the two. The twin reverb has dual speakers compared to the single speaker of Supersonics. This adds weight to the amplifier and makes it difficult to move.

Also, keep in mind that even the Twin reverb has that reverb issues!

So, the question comes, is fender supersonic any good? Here’s a table summarizing the comparisons.
