Palmer PDI-03, great piece of gear. I have one hooked up to my Mesa rig, Triaxis > 2:90 poweramp > PDI-03 - the rig is insanely loud when hooked up to a cab but I can use the simulator to record direct at any volume I want and even use headphones. It comes with ground lift to remove cycle hums and has a balanced and unbalanced outs for straight to desk or PA options etc. You can also switch between settings for different cab/speaker size - deep will give an extremely heavy boomy low end for monster power. If you decide to buy one get it from Germany for less than half the cost of the US retail price - do a search and you'll find a site in German, then email them in English, most Germans have excellent English so it should be no problem.
