Hey guys. So, I've been using my Fender Rumble 100 V3 for nearly 2 years without any trouble UNTIL recently. Been gigging a ton and so I've just been leaving it in the car instead of lugging it in and out of the house nearly everyday. (Lazy, I know) I live in the south so the summers get pretty darn hot. I had noticed that the power switch was getting kind of stuck but it would always power up once the switch was flipped. Well, yesterday I bring it inside to rehearse a little aaaand...nothing. Flip the switch and I get zero sound coming out and the LED won't come on. Have I screwed myself over? I intend on bringing it into my local music store but wanted to see if anyone on here could help me out first. Any thoughts, ideas, tips would be greatly appreciated. Thanks! AWG
Someone with the initials AWG (American Wire Gauge) should be able to fix it right up. More seriously take the amp to a tech and have it checked out. It could just be a failed fuse but it also could be much worse.
Haha! You've got a point there! Thanks for your thoughts. Let's hope it isn't anything seriously bad.
The main problem about this combo is its lack of quality. Check this out: Hey all, I'm reconsidering my move. Not sure what options I have, but this is a type of review like no other I've seen so far on YT: I'll look for more reviews like these and see what other people think about this. English subs are available in the menu for those that can't understand Spanish.
The manual states that the amp should not be installed near heat sources. Leaving the amp in a hot car probably amounts to much the same thing. Take it to the nearest authorized Fender Service Center.
Id say high heat isnt good. but leaving it in the car wasnt the issue. you already mentioned the switch getting sticky and now its finally gone dead. its just a cheap switch gone dead, no biggy new switch and good ive had equipment getting cooked and rattled to death in trailers and no problems. and then some amps get rattled to death. depends. a turd switch is a turd switch it will die on earth the moon or in a bomb shelter doesnt matter. they die when they die on the car forums a Holley carburetor fixes everything here a tort guard or a effect loop clean fixes everything lol
Andrew, what was the outcome? Did you get it fixed? Just this morning, the power switch on my Fender Rumble 40 died. It worked fine until this morning. Now, I switch it on and off and not only is there no power, but I can't feel the "click" any more when I rock it back and forth.
Very interesting and timely, for me. I just got back from visiting an amplifier repair guy near me, to fix my Rumble 40, and he said the same things the guy in this video said about the electronics. He says he thinks it's the power supply (the problem in my amp), and he can't get a replacement for it, and the schematics aren't available -- just like the guy in your video said -- and he said it would cost a couple hundred for him to open it up, confirm what's wrong, and tell me he can't fix it. So it appears these Fender Rumble amps are disposable, not fixable (at least not the electronics). I would be interested to hear from any TBers who were able to get the electronics fixed in these amps. Moi_, thanks for posting the video.
I posted on TB earlier this week that "heat and plastic don't mix," whether that's warping pickguards or cheap switches. It's probably just a faulty switch.
That's weird, heat cant really damage the actual electronics. If so, cars would be screwed. It could mess up speakers more likely, but sounds like a cheap plastic switch mechanism broke
No prob man. If you lived near me, I'd tell you to bring it over and troubleshoot it using my good amp to compare and a good multimeter. Try to open it up and look for any blown capacitors, blown fuses, anything burnt or shorted. Wish you the best
This ^^^^. The warranty is good for 2 years. Hope you haven't let it run out while trying to figure it out! .
Moi, thanks for the suggestions. I believe my problem might be the on/off switch, so I bought a replacement online and will attempt to swap it out and see if that does the trick. I'll post back and let you know the outcome. G-dog, my warranty has expired....alas....
Success! I bought one of these online https://www.amprepairparts.com/sw489.jpg It was a struggle getting the old switch out, but I finally wrestled it out, put the new one in, and the Rumble 40 is rumbling again. Phew....
Awesome! For future reference, is this a beginner project, or do you need some electrical know-how? (read: can I possibly electrocute myself trying this )
Well... you do need at least enough electrical know-how to make sure it isn't plugged in when you're working on it.
I was wondering that too, but actually you don't need electrical know-how for this particular repair, just a little common sense (I never thought I had any, but evidently I do). 1) When you unscrew the panel from the amp, there is one cable that you have to unplug from the inside of the panel, but it's easy to unplug it. You don't have to unscrew it or strip wires or anything, you just unplug this one cable connector. This is just to get the panel removed from the amp. 2) Then, to change out the power switch, you first have to unplug four wires from the old switch. The four wires are housed in a plastic housing or harness (I'm not sure what you call it). So they're easy to unplug from the switch. You just have to remember which wire goes on which prong of the switch, so I took a picture of it before I unplugged the four wires, so I could refer back to it. 3) Next step was removing the old switch, and that was the hardest part. I had to wrestle it out with a screwdriver and pliers. 4) The new switch was easy to snap into place, and then I plugged the four wires back onto the four prongs of the new switch (referring back to my photo to make sure I had the right wire in the right place). So if I could do the above, anybody can.
