So I said I use a Fender Rumble100. Well, I'm buying the 200 1x15" from Sweetwater and selling my 100 - I simply don't have space for two. Our basement apartment will never appreciate the lusciousness that is the 200, but it will definitely take me further. It's only 28 pounds, 6 lbs more than the 100, for the 15" speaker. Not only is it 200W, but the added benefit of the TRS output to plug into other cabs at gigs if we need it. I saw the 1X12" 500W cab, I looked, I lusted, and expressed a bit of necessary restraint and refrained from buying it also hehe.
I've used the 100 at gigs, but you're pushing it. Clearly the 200 will do way better. Plus my low B string will probably appreciate the 15" speaker much better ... all I ever played were 15s when I was younger.
You won't regret it - I like my 200 Combo so much that I bought a 2nd one after flipping the 1st one, despite already having some excellent amps...
