The size gigs it can do depends a lot on several factors like:
If in doubt, or if needed later, get the Rumble Stage 800. Only double the weight, but 10 to 20 times the power, with the exact same models and features!
- How many other instruments? I've played mine simultaneously, as the only bass, with 20+ other acoustic-only instruments such as guitars, fiddles, mandolins, banjos, and a dobro!
- How loud are the other instruments? It won't hang well with an ego-driven 100-watt guitarist, and/or loud drummer. It can work well with sensitive, listening electric guitarists and a like-minded drummer.
- Do you have reinforcement? If not using the XLR Out(s) to PA, do you have other amp(s) you can run the FX Send(s) into?
- How big a venue? It won't fill a large room full of lotsa people, or outdoor gig without using the XLR Out(s) or othe reinforcement(s).
Hope this helps.

The Stage 800 will easily carry a small to medium-sized room on its own and sound gear doing so. It doesn’t wince when you lay into either. I haven’t had the chance to play with an ext cab, but expect it would perform admirably.
I know it’s up there, price-wise, but to me its one of the few combos I’ve owned where I could unload all my other ones and be happy, and for me that’s saying a lot!

(Someone fogot to change the graphic from the Mustang version?)
I don't see where a Bassman amp icon shows where a "British Watts" or "Bri-Watt" amp should be. I'm probably overlooking it. Can you please give me an example preset name or number?
