What do you guys use? What have you tried? What do you love or hate? Let's get it out there. For starters, I run an ART tube preamp out front of my DAW to give the tones a little more feel and warmth. For only like $20-30 used on reverb, everyone should grab one of these or something like it to put out front of the DAW. Also considering getting a hardware tube screamer or boost to do the same. THE GOOD: Mercuriall U530 - A sim modeling the ENGL E530 preamp. This thing is amazing in every way and it's become my go to. Good for any genre. Built in cab sims chorus and more. Mercuriall Spark - It models a selection of Marshall amps so it's odd that I enjoy it so much being that I am not really a Marshall guy. Good for any genre. Built in cab sims tube screamers/boosts, delays, gates etc. TSE X50 2.0 - Another bad ass sim that to me kinda blends the 5150, 6505 and EVH amps together in various ways but compares more to the 5150 II than anything else. Good for anything with distortion and the clean tone is serviceable. Built in cab sims, delay, tube screamer, gate etc. S-GEAR - This is a collection of amps that is gear more towards blues, country, rock and maybe hard rock but personally I don't feel it has much to offer for high gains at all. It's my go to for clean and crunch tones. Built in cab sims, delays and verbs. POULIN / LEPOU FREEWARE: You will not get better freeware and that's a fact. He has ENGL, Soldano, Marshall and other sims that when combined with some decent IRs/cab sims can provide massive tone. This stuff has been around for a while and a lot of even the more expensive software still doesn't touch it. Honorable mention would be to the EZMIX guitar packages. They are cheap and really good for fast demos. I use some of their solo/lead settings, clean tones bass settings and other stuff in there. For the price, I like it. I wouldn't use their high gain settings over my other sims but there's some useful stuff in there. UNDECIDED: The Engl E646 VS - This one is designed by Brainworx and it is modeled after the ENGL Victor Smolski amp. I managed to get some nice crunch tones out of it but high gain wise, I haven't been able to really get anything that wowed me but I haven't given it a fair shake yet. I plan on buying the ENGL E765 shortly, does anyone have any experience with it? BAD: BIAS: I know there's a lot of Bias fanboys around here and hey, what you like is what you like but in my personal opinion, I think everything they have put out is a bunch of half assed garbage dressed up with cool graphics and options. They pay top dollar to the right names to demo their stuff and to put their names on certain amps or features and then people buy it. What you don't see in the video reviews and tests is that the FX chains are lathered with other high quality plugins which they have to be to get a good tone. My experience with BIAS has been buggy programs, false advertising and rude customer service. It's the no man's sky of guitar software. I can't say anything good about BIAS. I will also just lump stuff like Amplitube, Guitar rig and so on because it's all pretty crappy but if you are looking more for jus software to play with and jam along to songs or whatever, get it. Thermionik: I feel bad putting this stuff in the bad section because it's not by any means bad. I can just say that I worked my butt off with all the sims, all the cabs and honestly, I just could not dial in anything I would use on a recording. I think the developer tried to model too many amps and it just came out as a bunch of sims that are below average and really don't sound a whole lot like the amps they are modeling. Recabinet, master dither, Kclip and his other stuff is solid but I feel that with his sims, he should focus on 1-2 amps and use his talents to really hit a homerun instead of releasing 5-10 at a time. I can't think of any more off the top of my head. The stuff from Ignite amps is cool, their bass amp sim is top shelf but none of their sims really stands out.
