Wow.... this is just NUTS. After years and years of playing and owning pretty much everything that exists in the world, my favorite most loved and adored amp is a tie between this guy and the GB STL900. Both AMAZING amps, both available for under $500 used. The only other amp I've used that beats these in terms of overall sound is the EBS Fafner II.
I just can't believe how inexpensive these things are for what you get these days.
Too much gear, too little skillz.....
