So, with great skepticism I sat for an hour (benefit of having a small family run store, a Best Buy Music store, AND a GC right by work) and played the 5:50+ head through a Recto 4x12.
As a preface, I didn't love the original. In fact, it's what caused me to seek out a used DC, because the high gain tones just didn't do it for me, and the cleans lacked warmth. Just too sterile.
Whatever they did, they fixed it. In fact, in some settings this amp sounds eerily like my DC, and for me that's a good thing. The clean tones now are very close to Lonestar territory, and the high gain tones are DC territory, which I really love.
Strangely I found myself really enjoying the amp on the Crunch setting, with GEQ engaged, on 25 watts. Fantastic rock sound, and sounds amazing with analog delay.
I want to bring my DC, Warmoth and Strat back (as the owner of the store invited me to) to really A/B the amps and try it with my own guitars.
I could see selling the DC and moving to a 5:50+.
