i remember when i was running X-1 i could never get the serial number for GR and since it does not come with X-2 i just gave up and use my POD 2.o

hmm... you should really find that serial number or call Cake to get them to send it to you. GR isn't as good as TH2 IMO (especially the GR Sonar) but it is still usuful to have around. Also sometimes the upgrades to GR5 go on special and that has some cool stuff in it. I like GR5 better for bass than TH2.
