I'm mostly a headphone guitar player and found out of any amp sim that it is best to use a reverb with good control of early reflections to achieve the best feel when playing.
I've played with trial version of Aether from 2CAudio and got a very good results, but it is way expensive.
From what I have now I'm testing Scuffham S-Gear's reverb and a few freebies.
I think everyone would really appreciate if TSE will include a good reverb with controllable early reflections to get the most out of its product! I would pay extra just for that.
