Nice thread, cause as a HUGE fan of hypocrisy/pain/tagtgren, I bought the PSA 1.0 a year ago for 200 bucks, to catch that tone I just love. It's as if it had a little digital sound, but the good side of digital. With the PSA, Sansamp achieved to have a real unique electronic amp sound, and not something trying to emulate a tube amp.
I just never found a good tone yet because... I just have it, and nothing more (no cab, no power amp). I wanted to have it because I know I'll tweak it a lot when time will come and that was a good price.
Is it a good idea to use it in front of impulses, I mean, compared to some Revalver or Nick Crow's free vsts ? Did you compare the results ?
