OMG! They have NAILED the tube sound. NAILED IT!! Now...I am a major equipment & tube snob. Only play vintage American guitars, and tube amps that are NOT PCB. So, it was with skepticism that I was killing time after getting my taxes done that I stopped into a big box to kill time. I demo'ed the Tone Master Twin, fully expecting to be disappointed and WOW...sounded as good, if not better than my "77 Ultralinear Twin with JBLs. Also..the best, cleanest sounding reverb I have ever heard. Even better than the "Echo" on my '64 Gemini II. Has the surf "drip" that I love. Gonna demo the thing with my pedal steel on Saturday, on the way to my gig. If it sounds good with steel, I may hafta plunk down the Benjamins & put it on the card. I can't believe I am considering buying a SS amp. I will STILL be a guitar snob, though. No new production guitars for me.
