    I recently picked this up with a Squier bass on the cheap. Bass is fine, amp is not working. When I turn the amp on I hear noise (hiss) but, no sound when I plug in the bass. Cable has been tested with other amps. Any suggestions? Need additional pics? Is it worth it to try and repair?

    Looks like a V2. If it were me, I wouldn't waste too much time fussing with it unless I seriously needed it. In any case, ask around in here: Fender Rumble Club I'm sure one or two of them own the same amp.

    IF your seller can give you the original receipt from his new purchase in late 2013, or early 2014, you MIGHT can call Fender Customer Service about the 5 year warranty and see what they can do. It's been discontinued about 4½ years, so they won't fix it. But, they do honor their warranty.

    That's an original 2003-2009 first generation Fender Rumble 15. A brand new V3 Rumble 15 is $80 shipped all day long. If you can get that repaired for $45-or $50, do it.

    Does the unit have an Effects Loop? If yes try the old trick of linking the send and return with a signal cable.

    I contacted them. No such luck. Called Fender Customer Service. Nothing they can do without the receipt. Seller's also don't recall where they bought it. That might have helped

    Here you can see what happens as I turn the unit on and off.

    OK, that's a V1 Rumble 15. Get a schematic from Fender and find a competent electronics technician to trouble shoot and repair. A new Rumble 15 is $80 shipped.

  9. honestly, all I've got is maybe it's a connection somewhere, maybe cleaning the effects loop if there is one might help. maybe try listening to the headphone jack, as well if there is one, and clean that and your input jack too. I've heard of some using WD40 or contact cleaner, but while I'm sorta knowledgeable, I'm no expert, and I'd probably stick to contact cleaner. Maybe clean the pots, as well, just because they're there and it's open. Both your headphone jack and your effects loop if there is one are designed to bridge their connection if nothing is plugged in, so if something gunks up the jacks it can cut stuff up like that.

    Other than that, maybe a faulty component somewhere, but everything is visibly clean - doesn't necessarily mean anything, but when troubleshooting it's best to try the simplest and cheapest thing first and start from there. That, right there, can save you a lot of cash.

    WD-40 belongs nowhere near electronic equipment. Contact cleaner belongs nowhere near pots. Craig DeOxit only.

    In this case it doesn't matter, though in the old days that would have been a $30 - $40 repair
  13. There's a fuse tucked in there somewhere. I've had a couple of Rumble 15's and both blew fuses. $2 fix.

    I’m looking for a fuse. If it was blown would it still power on as the video shows?

  15. Classic case of me failing to read the full thread. Sorry, I assumed you had no power at all to the amp.

    Did you try different outlets in your home, maybe you have a bad ground?

    Not to be snarky, but as a former owner of these Rumbles and their Peavey equivalent, the value of the time you've already spent on this far exceeds the repair cost. #justsayin

    I don't disagree except sometimes tinkering helps me learn and if it was some type of easy fix I would have tried to do it

    I don't believe the ground would have anything to do with the input. Still powers on. I tried anyway. Nothing
