Issue with Fender Rumble 25

[thatjazzbassguy]

Hey team,

Bought this second hand Fender Rumble 25 just to have around the house whenever I want to practice a bit and been playing it for a week or two now without any issues.

Went on a holiday for 5 days, came back turned the amp on and I hear this noise that almost sounds like a detuned radio.

I've moved the amp everywhere in the house just in case it was a plug or picking up some interference but nope.

Have tried to upload a quick video but it doesn't seem to allow MP4 files...

Any help would be appreciated.

Thanks

Btw the noise is very loud, even though when plugging in the bass I can also hear it.

Might someone have had access to it while you were gone?

Not at all.

As with most all cases such as this, it's time to take the amp to a qualified repair shop.

Does it make noise with nothing plugged into the input?

 

[thatjazzbassguy]

Yeah I wish I could record it. That's what I get for buying stuff from Facebook Marketplace. It makes the same noise with or without the bass plugged in.

I have a guy who repairs amps but just never in my entire 30 years of playing had to deal with a bad amp. Guess I was a victim of buy cheap buy twice.

Even great amps need work sometimes- maybe you got yer next 30 years of trouble free really cheap?

(that is NOT how it works!)

Does it make the noise with nothing plugged into the front?

This is troubleshooting step number one!

 

[thatjazzbassguy]

Yup. Noise is coming with bass plugged or not plugged. I was hoping I didn't need to splash any cash into this as I bought it second hand and if I need to take it to a guy it's probably going to add up to almost the price of a new one....:/ Oh well.

On a separate note, anyone familiar with the Hughes and kettner Basskick505 Dynaclip? Had the option to go for it for around £60 but went for the rumble instead...

By the way, not sure what the issue was but I plugged the input jack three times and the noise kept reducing each time and the last time it went away.

Could it be a dirty jack input? Is that easy to clean?

 

[agedhorse]

Could be. If it’s working now, leave it alone!

This model is not supported under any factory service programs, they are a replacement item under warranty. Any qualified service shop should be able to repair one, but it will likely cost more than it’s worth.

My R25 a couple of times has made a popping noise and the bass volume cuts out. A tiny bit of DeOxit into the input jack clears it up. May not be a recommended solution!
