I am looking for a pedal or two that would serve as a multi effects pedal and a looping station. The only thing is that the combined price has got to be under $300. For loopers I've been looking at: Zoom B3, Boss RC-2, Boss RC-3. For Multi effects I've been looking at: Zoom B3, Boss Me-20b, Boss GT-6B. What do you say I should get, and I am totally open for other suggestions as well.
