One thing to consider is that plenty of real amps sound awful. When it comes to tube amps, some can sound awful one day and great the next one.AC222 wrote: ...I've owned or played them all and I honestly feel that the Amplitube stuff (newer Custom shop models) sound the most like real amps...
I have not owned or played them all. Probably my only mainstream amp has been a JCM-800 that I had in the 90s. These days I've only kept a Cruise MQ-4 and an original zenTera.
I was lucky to attend an amp shootout with dozens of high end and vintage amps. There was a row of 5 Gibson amps, same model, each sounded different. IIRC I liked one. Similar for 6 old Vox amps. In that case I liked two. The nicest tone (to me) came out of a Dumble amp. Out of perhaps 50 amps, I don't think I liked more than 5 or 7. Not that they were bad, but at best some just sounded OK. Would I want a modeller that sounded 100% like most of those real amps? No.
I haven't used Amplitube in a long time. IIRC, the Metalhead amp sounded awful, yet it was supposed to sound exactly like the original.
Back when I had a few tube amps I tried different things to get the sounds I wanted, from adjusting the bias to swapping tubes and trying different tube types and brands. With modelers it is no different in terms of trying different things, which can be as simple as removing digital fizzyness via an equalizer. For me some can work better as practice tools (i.e., they have a metronome, the ability to slow down songs, etc.) and others are great for getting a polished sound quickly. It's great to have so many choices these days.
