Old post and all that...

I recently purchased a Rumble 500 and the matching 2x10 cabinet. I would like to change the knobs too, but no matter how hard I pull, they don't come off. I don't want to break it, so does anyone have any ideas? Are they glued to the thing or something?

Thanks.
You did loosen the knobs' set screws, right?

... ... Try prying the knobs off with a very thin flathead screwdriver. They're not glued but they can be quite tight sometimes. Just be sure not to modify anything that can't be unmodified in case you have a claim within the 2-year warranty time period, though! ... ... ...
I use tools like these ... ... ...
PSA: the red ones are $.02 cheaper.:hyper:

For these types of jobs I have meticulously curated and collected a finely crafted set of tools like this over several decades. I keep each priceless piece strategically located in a part of my house, or maybe garage, or tool shed, that it is least likely to be be used in, so that they don't feel taken for granite. It's just so much fun finding each and every one, or as many as I can, for whatever project comes up, in order to determine which one works the best at that particular time!

Did you buy it new? If it was used, maybe the previous owner glued them on. Mine came off with little to no effort. Good luck, it looks waaaaaayyy better with the chicken-head knobs!
I switched mine out for these. Slightly smaller and easier for my fat-ish fingers to get holt of(stock-white, new-black)
EDIT: they do have set screws

Always use the proper tool.
Or whatever else is handy.

I made a knob puller for my Rumbles using an old 35mm film canister.
Five minutes with an Exacto knife, scissors and a file.

Leave just enough of a "lip" on the bottom on each side to slip under the knob. Squeeze the sides together to grip the knob, and pull up.
 
Brilliant!
BTW, what look like splits up the sides of the canister are intentional cuts.

In order to use the puller you place it over the knob with the crescent-shaped edges pressed in under the knob, and then squeeze the plastic sides until you're actually gripping the knob. The thin plastic "lips" of the clear canister I used aren't strong enough to pull the knob without support.

Squeezing and physically gripping the knob works fine, but I had to make the side cuts to make it easier to squeeze the sides in.
 
Dear Rumblers,
Club member and friend @GonePlaid got a phone call at 6:00 A.M. this morning saying that his 48 y/o daughter and best friend Jamie had passed away. We don't at this time know what happened. He won't be on line for a while as he’s basically in shock right now.

Indeed, Mike must in such unimaginable pain right now. Let us all send him our best prayers or wishes for strength to bear this extreme grief with good grace. 😢
 
Hi, may I ask if the Rumble 500 would be suitable as my only amp for practice, rehearsals, and small gigs?


My main concern is the volume for home practice, and whether it’s possible to use it at night. Can the volume be lowered enough for quiet practice?


This would be my first “big amp.” I have a Rumble 40, but I find that it distort and has a tendency to fart if i up the bass eq on certain notes and frequencies, even at lower volume. I kind of have a more enjoyable time using my headphone amp or running through my Focusrite with a bass plugin on my PC and playing through monitor for practices.


I was originally considering the Rumble 100, but after seeing the price of the 500, I thought maybe I should just go for it instead.

I would think it would be fine - all the V3 Rumbles have headphone outputs in case you want to go total silent or feel it's not quiet enough. But honestly, I don't think it's going to be an issue. Yes, it may be a little louder at lower volumes due to two speakers moving vs one speaker in the Rumble 100, but you would also be well suited at a practice or gig with more speakers and higher wattage.

Woo hoo, woo! @wooheehaa, you are now member #1898 in the Fender Rumble Club. Congratulations and welcome. Please put that number in your TalkBass Signature for safe keeping. Then make yourself at home here and on your Rumble Club Wiki page, the repository of all Rumbling wisdom and knowledge.

woo the R500c can be whatever you make it to be. Sometimes I feel like the 2x10" speakers of my 12-year-old R509c are a bit much for low volume night practice. But, it may just need a slightly different EQ for low vol. Or use headphones. Or use your R40. You wouldn't get rid of that, would you?

So how about telling us a bit about yourself, woo, such as your bass experience in general and your Rumble journey in particular? You'll fit right in here since we have all kinds. But we all love to ... ... ...

Rumble On!
