The competition rules were for an un-mastered mix, but since the contest is officially closed, I thought I'd go the whole hog with it. Mixed and "mastered" entirely on headphones, so your milage may vary.

The Liza Colby Sound - Oh Baby (Gearfest PureMix Contest Track)

12ax7 model amp test 2014-03-18

Tone is a lot tighter and distortion cleaner in this build. Problems with dynamics (especially on the pinch harmonics) remain an issue.

Confined - EVH 5150III VST Model Test 2014-03-20

Improved tube dynamics and transient response. High end sounds smoother, low frequency response feels tighter. EQ, cab and mic impulses are IDENTICAL to previous version.
