After lurking theses forums for years I have a post that I think is worthy to get out there I'm gonna try to keep this short but the TL: DR scoop is: "A couple capacitors in my Fender Rumble 100 v3 blew up while it was still under warranty and Fender, nor Guitar center, nor my local Fender dealer couldn't help me till I bitch to Fender my self for a second time, and got a new amp for free" I had a lot of difficulty finding anything on this issue and either its a super isolated incident or no one has said anything. Day 1: A couple capacitors in my Rumble 100 blew while I was playing it-there was a loud POP! associated with a bright flash of light and smoke from the amp. I called Fender and they told me I should go to an authorized dealer 1hr 45min away. Instead I called a local boutique music store that sells Fender gear and they told me they can take care of the warranty work (sending it to Fender) as long as I have the receipt even though I bought it at Guitar center. I actually got the owner of the store on the phone and he told me that they are a authorized Fender dealer. Day 2: Get my receipt and the amp over to this music store. 3 days later: I get a call from my local music store saying that they can't help me because I bought the Grey Limited edition Rumble 100 from Guitar Center-which was a guitar center special thing. I call Guitar Center again telling them what this local store told me and again they won't help me if I didn't get pro-coverage. however they give me the warranty people phone number for Fender and I call them. I get on the line with a Fender customer service rep. I tell him my store up to this point and they tell me I have to go to this service center 1hr 45min away. At this point I'm getting sick of this, this Rumble 100 broke under warranty and no one will do anything about it!!! I give they guy a lot of s**t (not going into detail here) and he them talks with his manager. The solution was for me to send a video to them proving the amp is broken, the sales receipt, and the serial number, and they'll send me a new one. I get my amp from my local store, send Fender what they need and BAM! 5 days later in the mail a new Rumble 100 get's dropped off at my apt. Don't get my wrong here guys, I love Fender and what they have done for the bass guitar and bass amps, but getting gear repaired under warranty shouldn't be this hard. I'll sways be a customer of theirs for as long as I need kicks ass amps and maybe a p-bass down the road. I'm just posting this because no one else has seem to have the issue and putting it out there may be able to help other navigate warranty service. You should always try to go to the store first before calling Fender. What blows my mind about all of this is two things: 1. Why does Fender not know that this local store is an authorized dealer? 2. It's insane that with all the money and logistical power Guitar Center has that they can't help me at all. Since it no longer matters if I get my broken Rumble 100 repaired anymore, I took it apart and found the issue....two. little. surface mount capacitors. burned up and did the whole thing in.
