Who out there is into guitar amp sims? I've tried most of them at least once over the years. I never loved any of the one trick free ones unfortunately. I still have some version of Overloud TH3 that is okay. I haven't yet tried TH-U but I've read some good things. The first computer-based amp sim I really liked was Positive Grid Bias Amp. I have that and Bias FX, but I own Bias Amp 2 and Bias FX 2 now and those are my primary guitar rigs these days (plus a few pedals I built in front of them). I've also owned a lot of the hardware sims like the Pod HD Desktop, Helix, Boss GT-5, Axe FX 2, and Kemper. Of those, the Kemper felt the best and Axe FX probably sounded the best. I never really got along with the Helix tonally despite it being the sexiest to use. The Pod HD Desktop lasted the longest (several years) mostly because it wasn't worth a ton to sell.
