Thanks to everyone who responded to my confused amp thread. Taking some advice from there and dong a little more research, I've come up with the following tentative plan: 1. Hartke 3500 amp, in a rack bag so it's easy to carry. 2. Avatar 15" compact bass cab at 8 ohm. This will be the first cab I get, and combined with the 3500 amp will make a nice combo for smaller situations and to start out. The amp will push 240 watts through this cab alone. 3. Avatar 12" compact bass cab at 8 ohms. I'll get this later, when I can afford it, and I think it it will be a good match with the 15. The amp will push 350 watts at 4 ohm between the 2 cabs. I know some people suggested more wattage, but the HA 3500 is the most powerful I can afford, unless someone can suggest something more powerful at a comparable price. I am interested in hearing some opinions about the pros and cons of a rig like this. Another thought I had was to get the 2x10 cab and then add a full size 1x15 sub, but that will be more expensive in the long run and also seems less versatile.
