Hi @BK .
Absolutely. When it came out it was a very advanced amp with capabilities that are hard to find even now.
Specifically, it’s two amps in one. Both a solid state and a tube amp. You can use either one stand alone or you can use them both at the same time and blend them.
It’s a pretty amazing amp. The only thing new amps might have over it is lighter weight.
If you want to read over the specs and features, take a look here. The GBE 600 is #49 on this page.

Lastly, the engineer that designed it works for Mesa now but still does work on the Genz Benz amps. He is Darkhorse on the talkbass.com forum.
