Lovin the Bogner Red, all the Peavey 5150 type models, Brit Mod, Plexis, Triaxis, Super Reverb, 59 Bassguy, JVM, and Bludojai Lead. Probably a lot more, but just haven't had the time to mess with very many other models yet.
The Bludojai is just insane for getting a thick, smooth, sustaining lead tone. Great for fusion, Santana, even blues with the drive backed down.
So far, the only ones I haven't cared for are the Leggy, VH4, and FAS Modern models. But, I rarely used them much anyway.
That leads me to an interesting question. With MIMIC having been applied to the models of real amps, will the theoretical models (i.e. FAS Modern, FAS Lead) be sub-par now? I really haven't had time to spend on any of them to make a judgement yet.
