I went to a buddies house to do some guitar recording and he plugged me into his DAW and it had such a nasty tone it blew me away. I asked him what he was using to get the tone with and he told me about TSE Audio x50. I've never had any experience with this AMP/CAB sim but I have played around with various impulses and stuff in cubase like LePou plugins and guitar rig but always had pretty lackluster results with a tone that really lacked any balls/clarity. so I came home and purchased TSE x50 and have played around with it for about 30minutes after installing and have already come up with a tone that blows anything else ive tried out of the water. any of you guys have any experience with x50? or any other sims that really standout for that matter?
