I like the unique effects and amp selection of the G3, but I find it's pretty bad at doing glassy crunch kinda sounds. Everything has this sort of "warm, polished" feel as it to say "hey look I'm a modeller but I don't sound too harsh or digital!" but as a result it kind of lacks a certain nastiness that you tend to be able to dial in with a lot of amps. I miss my Pod HD sometimes, but I prefer the FX selection of the G3 I think. The 500 was physically too large for me as well. What else is there out now that has similar functionality to the G3? It really is very good for the price, but it's better as a pre amp multi-fx than an amp modeler I think.
