I have a Fender Rumble 200. ... ...
Congratulations, you should check in at the TalkBass
Fender Rumble Club to hobnob with other Rumblers!
... ... I don't think I need more than that, but if I did need more power (mwa-ha-ha!), I'm hoping to understand the options better. My understanding is that the Rumble 200 really operates below 200w unless you connect an external cabinet. ... ...
That's right, Rit, the R200 outputs up to 140 watts standalone. You need an 8 ohm 100 watt capable cab to get the full 200 watts.
... ... As far as I understand it, my options are:
1. Another Rumble 200, connected through the FX loop? Is there a downside to this if I can find it cheaply used? ... ...
That's great! They connect with an instrument cable from the FX Send of one to the FX Return of the other, and the Sender completely controls the Returner! Plus the added benefit of a spare amp if something happens to one. The only downside is with used Rumbles having no warranty, but may carry someone's hidden abuse!,
... ... 2. A Rumble 210 cabinet ... ...
Yes, that is a very valid option, though not everyone can actually hear a difference between the 10" and 15" speakers at gig volumes.
... ... 3. A Rumble 115 cabinet ... ...
Oh, yeah! Now yer talkin'! For a minimal investment you get a perfectly matched cab, with a larger tuned space and the
exact same 8 ohm 300 watt speaker as in your R200! Plus the
tone enhancement of identical
stacked speaker coupling!


... ... 4. What about third party cabinets? What specs should I look for? Can I get something cheaper/better than the Fender cabinets? ... ...
We-ell, ye-es, you just need an 8 ohm, 100 watt capable cab. Yes, you can get ...
a. Cheaper, but it won't be as good, or
b. Better, but it will cost more,
c. Not both together.
... ... 5. Sell the 200 and get a 500? ... ...
Yes, the R500, at 350 watts standalone, would be a very big jump in volume! If you really want that much more, I'd recommend the Rumble 800 combo, at 400 watts standalone, or just 100 watts when you flip the 1/4 Power Switch! It's quite flexible that way.
... ... I'm going to check with the band leader and sound guy to see if what I'm bringing is already enough. My thinking is that if I need more, chances are there will be a house sound system that I would plug into.
There is not always a house sound system capable of handling bass guitar when you need it! I assume from your writing that your sound guy doesn't currently have one either.
Remember, you can combine your listed options, too! You could start by adding a Rumble 115 cab then, later when playing bigger venues, add another R200, R500 or R800 connected via FX Loop. Then, still later when you really hit the big time, add cab(s) to the 2nd R200, R500 or R800 (the R800 can drive two 8 ohm 300 watt cabs!).
Heck, an R800 HD head can drive one 8 ohm 400 watt, up to four 8 ohm 200 watt, cabs (think R410s) if you want a really modular system that can handle anything!
