To me, one of the Holy Grails of guitar sounds is at the beginning of Megadeth’s Almost Honest. I created two impulses based on this with the results you hear above.
You can download the impulses here, one left and one right and put them in your favorite impulse loader. If you don’t have one already, NADIR from Ignite is free, and the one I used for this: http://www.igniteamps.com/en/audio-plug-ins
For the amp sim, I used Vadim Taranov’s JCM800 with the default settings. You can get that here http://pvamps.blogspot.com/2016/07/jcm800-1986.html
