The one thing that pleases me more than buying basses and gears is help others spend on their basses and gears, 
Without reading manuals, I was able to do some adjustments on the effects. It’s simple enough. So far so good it’s just the matter of testing all,of the parameters and find what I like. It’s funny this is pretty much the same as pocket GT, katana go, dual cube bass, and Waza Air bass app I already have but this will be the first time I’m doing the proper setup.
The music store where I bought my bass recommended a Rumble 15, about $100, I think. It suits my needs very well as a beginner who is just playing at home.
so first world problems
seriously though, it does look good. nice review.
I’d highly recommend spending $20 more and get the Rumble25. The 8” speaker sounds weird when the don’t have enough watts powering it. The 25 is a gold standard in entry level bass amp.
I picked up the Kanata 110 today. My decision on a amp was a long time coming. Tired of playing unplugged so I pulled the plug 
Second this from my experience, no frills but sounds good with heaps of volume.
I played with electric drums and two loud guitars and still only got to 3 on the dial.
I am only thinking about upgrading because GAS
Hi @Gloucestre, what amp are you speaking of?
Don’t let an amp decision hold you back from getting your bass. You can learn to play unplugged until you find your amp.
Josh, recommends the Rumble 40 for a great amp. He has a video on amp reviews. @Al1885 and I just got the Katana 110.
I am responding to Al (click on the tiny avatar and it will take you to the post), I 2nd the recommendation for the Rumble 25.
I believe rumble 25
Congrats @Linda you’ll like the katana. I’ve now spent hours on mine and I’m loving it so far. The default “katana” tone is quite delicious. It feels almost the same as my Genzler BA 10-2 Array costing 4 times more.
I reckon I’ll be getting one at some point
Highly recommended. The katana guitar amp are already at their 3rd gen but the bass is staying strong original gen.
Sure I wish that the app is more like the guitar app but it’s good enough.
The deal is out there for sure like everything else but it when you find a good deal not when you need it then you’d get the best price.
I paid $237 shipped from proaudiostar. It was listed as opened box but it’s not it’s still factory wrapped.
I got my RB-210 for $176 but it was 2nd hand. It was (is) in perfect shape though and even had the caster’s put on it.
Sighs, looking at Australian prices
So, is there a big difference between the 15 and the 25 as far as sound quality and volume? If so, I may invest in the 25 a bit down the road once I have more bass experience.
I had a Rumble 15 for the first year and a half learning bass (I took some breaks lol) so I lived with it for a long time and I never used headphones. I wouldn’t recommend it. It sort of sounds like its in overdrive with the volume up even slightly. If that’s the price point you are at and are only going to use headphones, maybe it would be ok, but otherwise it is kind of like a toy amp. I bypassed Josh’s recommendation for the Rumble 40 and got the 100 last week, and there is no comparison between the quality of the sound between the 15 and the 100. I feel like for the first time I can actually hear what I really sound like cleanly, and what my basses sound like. I think that’s an important consideration I should have been more aware of earlier, it sucks to have your equipment hinder your progress by sounding crappy. While the 25 isn’t going to be as good as the 40, where you get a lot more EQ and other options, I’m guessing 10 more watts for like $40 would be worth it with the 25 over the 15.
This may be obvious, but keep an eye out for sales. We’re approaching the holiday season, and I’m sure Guitar Center and other places will have some good sales. I got a really good deal on my Rumble 100 due to a sale.
Another factor I think people sometimes overlook when buying their first amp is cost long term. If you plan to forever play bass by yourself in your bedroom, then a Rumble 40 or whatever may be fine. But if you have any aspirations beyond that (like, you know, playing with other people), then you will have to upgrade when you want to do that. I mean maybe a Rumble 40 would be ok if you’re playing jazz with a drummer only using brushes and other musicians play soft, but anything beyond that, you’re going to want more.
Yes, you can also get some money back by selling your starter amp, but you probably won’t get it all back. So if you get something now that will last you a bit longer, you’ll likely save money in the long run vs. having to replace your amp in a few months/years.
Believe me, as a bass player, you WANT to play with a good drummer. Yes, playing by yourself with backing tracks, or playing with other instruments and no drummer can be fun. But it doesn’t compare to playing bass with an actual drummer. The real joy in music is playing with other people, and as a bass player, one of those other people really needs to be a drummer. Trust me on this, you’ll thank me later. 
In general watt equals volume but not always. It takes more of several things to produce decent low frequency tone.
It’s diminishing returns, too. With everything else equal, doubling the wattage increases volume by 3dB. To double the apparent volume it requires an increase of 10dB, or three doublings of the wattage - in other words, to double the apparent volume you need 8-10x the wattage, if you change nothing else.
In terms of low end tone I think most amps actually do okay though. All of the popular combos have 10-20dB of falloff down at the B to E string fundamentals, so you’re hearing a lot of harmonics with all of them anyway.
