Couple of combo/cab questions

Buy the Line 6 Lowdown, it's a 400 watt rack mount head, small in size but big on power, it's also a modelling amp with usable bass effects, and it's about £180 so that's around $120. There's no reason why you can't use a guitar cab, but a bass cab is built to match the lower frequencies of a bass head, and don't forget, the cab needs to be able to handle the power of the amp and run on the same ohms. I prefer a 4x10 cab, they give a more instant punchy sound than say, a single 15" but it's down to personal preference. Just to go back to Line 6, my lead guitarist, who is absolutely awesome!!, ( check him out on YouTube, TheRizingForce ) use a Line 6 Spider 75 watt and he drowns the rest of us out, he also uses an Ibanez Jem 7 which once belonged to Steve Vai and he paid ten grand for it so the Line 6 is obviously up to the job. Thanks
