My amp died! Been using it since 1996. With all the changes in technology, I've been looking at a different approach: Anyone using Stealthplug into a laptop with Amplitube for live use? The rest of my rack is fine, with a great power amp and a Carvin 4X12, so I thought I'd check out the idea of using Amplitube live. Reports are that latency is zero when it is set up correctly. Anyone using this?
