I notice that many of the TBers here purchase amps and cabs without testing them, based on opinions and reviews alone. I see this is a common trend with Schroeders and Avatar speakers since they are harder to get a hold of than an Ampeg or a GK...Obviously you are taking a risk in doing this since you cannot take your bass with you, plug into a rig and play. What are your views on this? Have you ever purchased an amp or cab based on research and other people's opinions? If so, what was the outcome and would you do it again?
