I am so impressed with the UA-4FX I'm going to give them a free plug.

The UA-4FX comes with a copy of SONAR LE and also runs either in MME or ASIO mode and a bunch of FX onboard.
We plug the guitar directly into the unit and on a separate SONAR track the output is sent directly to the amp and speakers. With the
"echo" button in SONAR on and ASIO on (to stop any latency) any FX on the track (like the GS-201) is also sent and can be heard even when not recording. The wav track recorded remains "dry" but of course on playback is fed through the GS-201.
