Since I purchased the 500X a few years back, have been in love with modeling and using Line 6 products. They are very user friendly, easy to use and it's really up to the user to create great tones. I really enjoy the Custom Tones forum to upload other individuals patches. One thing I'm disappointed about though is a lack of modern tone that just rips, bites and cuts through mixes.
Feel like there's a big emphasis on popular and classic when there is much more variety to be had. There's a Peavey 5150 in presets but no JSX which was a phenomenal sounding head. Options for Mesa Boogie products are available but no Randall products. Dimebag Darrell played Randall and is known widely around the world for his shredding. Scott Ian played Randall, Kirk Hammett plays Randall. Even Laney heads would be cool. Would love to see a Framus Cobra in the arsenal someday as well.
Also, I see a lot of options for Celestion speakers but Eminence makes fairly good speakers as well.
