There's an Ampeg SVT 50 Isovent cab at my local MusicGoRound for $400 and I think I might jump on it. The only thing I'm concerned about is possibly not having enough volume with it. I play in a 3 piece rock/metal band and I'm wondering if 600 watt rms handling + the 2x15's and 2x10s will be enough to keep up and be heard. I like a deep, smooth bass sound with a slight bump in the lower midrange. Right now, I have an Avatar B410 Neo w/ a Peavey Max 700 that doesn't have enough low end to satisfy me(I think it might be because it has 1st gen. neo drivers without the extended x-max). Would someone please help me make my decesion?
