So you say S-G is good for "regular" low gain sounds?
i LOVE it.
i feel the same as you, super high gain sounds weren't of much interest to me, i wanted something on the lower gain/responsive to picking dynamics side of things. i really wanted to like magix' vandal, as i'm a big fan of sascha's work, but it just left me kind of meh.
tried out s-gear....opened it up with the default settings, played for a half hour straight before moving a knob. it just made me want to play. i can't say enough good things about it. the amps sound good. there's tons of room to manuever in the 'in-between' zone of clean and distorted, which is where i usually live. it can do high gain in a non-metal way. the high end sounds nice, not all shrill and fake. the 'sag' knob really adds a nice squishiness. the cab sims are good, and for the scuffham sims, he has a grid where you can move the mic front to back, on the cone to on the edge, which makes a huge difference. at first i was like "option anxiety!" but in practice it's really quick and easy to move "the mic" around and find something that works.
i haven't messed with the effects much, but i can say that the default reverb is basically perfect. i just leave it as is pretty much all the time.
i got it because i like to be able to record guitars quick and easy, while standing in front of the monitors (i avoid phones as much as possible). i figured i'd use s-gear just to have reasonable sounds to track with, then go back and reamp the di's later. having gotten a few tunes together though, i'm totally happy with the sounds as they are and will likely just leave them. which was a nice surprise. sent rough mixes to a couple friends, who were both like "those guitars sound great!"
so yeah. big fan here. one caveat: it's kinda wonky in reaper. sometimes reaper will hang when trying to open projects with s-gear on the tracks. i figured out a workaround, and the designer is looking into it, but that's been an annoyance.
