Hello i have just bought a new fender 212r amp and i have gigged with it for around a month now. I have noticed that the amp keeps cutting out towards the end of the second set which never ever happened with my previous model (which was the same make). Yes the amp gets warm like any amp would playing it for a length of time but its beginning to become a problem at shows as i dont know when its going to cut out next. I use a seperate signal boost effect pedal to help the solos cut through the mix i was wondering could this be the cause although i have the clean on volume 2-3 and distortion on volume 3-4 so im not exactly driving the amp to death?? Any help advice gratefully recieved otherwise it looks like i may need to buy another amp. This would be a shame as i think its a great amp for value for money. Many thanks

Numbers on volume controls mean very little as there are too many things that affect the level. If you are really driving it hard you may be causing the amp to go into thermal limiting. This is a 100 watt amp so there is a limit. The sound level from it probably can easily exceed legal limits. You should get and use a sound meter. If the amp can create 100 Db that is all you need. If you stay in that environment over a few hours, you are a candidate for hearing aids in the future. I know several musicians that are in this condition and now are wrecked. Remember that loud does not equate to QUALITY... Your group should have a sound level meter and with that you can tell if the amp is performing as it should. One thing to be careful of is high frequency feedback, even that above what you can hear that heats up the amp with frequency output you are not using. Make sure your guitar cannot "Hear" the amp. Also be careful of boosting the high frequencies. Also be careful of large bass pulses that you can see drives the speaker cones to the limit. If the cones move too far, the voice coil leaves the active magnetic area causing excess current and amp heating. Make sure there is free airflow around the amp and especially the heat sinks.

I bought a Fender Frontman 212R back in March of this year. It worked brilliantly for almost six months, until July 26th, when during a jam session, the audio randomly cut out. Upon inspection, it appeared...

Try using your guitar cord to plug in and out of the headphone jack several times while unit is on. There is a circuit that disconnects the speaker when using headphones and the circuit is activated when something is plugged into the headphone jack. This "switch" can get dirty and cause the can get dirty and cause the problem you describe.

Hello! I was recently playing and found out then whenever I play specific notes on any of my guitars, my Fender Frontman 212R will buzz. The notes that always buzz are drop C, drop C#, any A note, and...

There is something resonating with that note frquency. Often the grille or wiring inside will rattle at certain frequencies. You need a sustained source of these frequencies to find what is causing the noise.

My Fender 212R 100W 2x12 Guitar Combo Amplifier keeps on cutting out. The guy I took it to says there is something wrong with the cylinders? I also could have heard that wrong. I honestly don't know much...

You had best get a second opinion! When somebody says "there is something wrong" means they don't really know the details enough to give you an estimate even. If the amp cuts out sharply I would suspect that: 1. Bad volume control 2. Cracked circuit board 3. Bad solder joint on circuit board 4. Bad jack. These are in order from least to most likely.

Hey, I brought my Fender 212R back frm a gig the other day and when i turned it on last night the reverb was dead, simply not working at all. I checked the back of the tank and its plugs were firmly...

Your amp uses a "reverb tank" that has two or three springs that are suspended. One end of these springs are driven by a transducer and the other end the vibrations are picked off with another transducer. If you dropped the unit, possibly the two cables that go to this tank on the bottom of the cabinet have come loose. other possibilities are the transducers have been damaged... or one of the cables has broken or the electronics that drives this and receives the return has broken. If you are not electronically adept, the only DIY is to check that the cables that plug into the reverb tank at the bottom of the cabinet are connected. The tank is often covered with black cloth like plastic and the cable have RCA type plugs that plug into it.

When i turn on my 212R it turns on in drive channel. if footswith is plugged in, then it turns on in the clean channel, but after switching in drive it is impossible to switch it back in clean channel. What could be wrong? Swith position doesnt change anything and it seems like switch is OK.

Have amp only 2 months & clean channel is muddy. it was clean when i bought it. its somewhere in between clean & drive

Test if the sound is clean using the headphone jack.

IF IT IS CLEAN in the phones, you have probablydamaged the speakers with excessive volume causing the voice coils to rub the pole pieces due to heating. If you can reach the cone either front or back GENTLY push on the cone and listen for ANY rubbing noise.

There are also electronic component problems that can cause this IF the headphone test is also muddy sound.

About a month ago while on a gig, I noticed that the amp was cutting out when I played solos at a high volume. I play at barely half volume now, and if I go any louder, the same thing happens, it cuts...

Not likely preamp tubes. If they cut out they would fade slowly then come back slowly...

First check for marginal input jack. These take a beating and get loose and poor contacts. The vibration can cause the contact to be lost.

Also volume controls can get marginal...

Try to catch it in the act and tweek things to find someting that is affected.

Another common problem is contacts on jacks meant for effects inserting. These pass the signal through switch contacts when nothing plugged in and those contacts are "junky" to say the least.
