Yeah.. I paid top-whack for me brand-new 600 back in the day (they just didn't exist on the used market), and while it was beautifully built and featured, and LOUD, when I realised it didn't have 'it', I had to sell it and lost a fortune. I always regretted that.
Incidentally, the other amp along these lines that I did love was the Genz Benz GBE600 (which I assume Agedhorse had input into). That was just as nice, but for various reasons I had to let it go.
