Man oh ma, gotta tell all you guys , I have been searching for an old model, 80's, horizontal power switch 800RB for 3 years .

Finally found one for $310 shipped, this is f...ing ridiculous!!!

I have been playing bass for 47 years, this amp is unbelievable!

Played it thru my custom built 1 15" Eminence 15" kappa pro 15 hlf cab.

There is nothing more versatile !!!!!

If you can find one of the old one's. , BUY IT !!!!!

What's the deal with the horizontal switches? I had a vertical switch one for awhile, and it was great.

Supposedly no difference. The horizontal switches were on the first iterations of the design. Any 800rb sounds good, I think it's just more of a "badge of honor" type thing. It means mine is 30 years old, and can stomp the livin' $#!+ out of newer amps rated more powerful than it is.:)

It's a combination of good design/honest power to begin with, plus filtering out the sub-lows so it doesn't waste power pushing out what most speakers can't do anything with anyway, and a high current capacity in reserve, so it can handle big transient spikes coming through and play loud without getting squishy/compressed, etc. Just the right combination of a few things.

If TC made it, they'd call it 900 watts or something.:D

Should add that it's pretty light. Compared to what was available in the mid '80's, it really is one of the first lightweight, with honorable mention to Walter Woods of course. Uses I think a class H power design, whatever that's worth. It's also convection cooled, no fan, dead quiet for studio use but you can crank these things all day long in the baking sun and they don't overheat. They can also do great warm/fat tones in addition to the growl and "modern" tones people think of as GK.

Obviously, I'm a bit biased here, but they're fantastic amps.:p

I do not know if they are class H or not. I kind of doubt it actually. I think it is just a well engineered design with not a lot of superfluous metal/wood in the case to add weight. They do get hot, believe me I have played some 400RB and 800RB amps until they got too hot to pick up with your bare hand.
From what my meager understanding of amplifier classes is, it would kind of contradict the "GK sound" to be class H. The GK growl wouldnt be acheivable?
