I posted a related question a while ago but I want to get a little bit more specific now. I own the GK Backline 210 and 115 cabs. Both handle 200W @ 8 ohms. What do you guys thing about the Ampeg B2R head? Is that a decent head and will it work with the cabs? It puts out 350W @ 4 ohms. Is that too much for the cabs to handle?
