No snark intended but your question doesn't give enough info on what you are looking for. In terms of what? Rated power? Actual power? Reliability? Tone? Help us help you.
Built like a tank,weighs almost as much,and able to survive whatever you can put it through..Great tones,very user friendly controls,powerful,reliable,and affordable..there's a reason they're so well liked!
Yup. Also, if you look hard enough, you can find a good used one in the $300 range. Also, these things are literally bulletproof.
Hmmm lets see.....the first one came off the G-K line about 30 years ago. It's features are often copied but not duplicated. It has been a favorite of backline companies for decades because it is reliable and sounds darn good. It always seems to outperform its ratings. It is very versatile. It is still in production today. I have one and it will never be sold. I let someone borrow mine and I almost had to show up with a gun to get it back. That enough for now....
The TB archives are loaded with posts about the 800RB. The only thing that has changed is some units changing hands since those posts were written.
What everybody else said. I've had mine 10 years with only 2 small repairs, a power switch and something else minor.. Sounds great by itself, but add a Sansamp Bass Driver (lightly blended) and it sounds pretty freakin cool. Glue the knob caps on right away if you get one.
Mine dates to '89 and still has all the grey knob centers, first one I've ever seen that wasn't missing them. I just picked this one up recently in pristine condition. I used to have one years ago that I ever so stupidly sold. That one was missing most the centers and was pretty scratched up. This one's going to the grave with me.
I picked up a very well used one about two months ago, it looks like it might be from the eighties. so far I really like it, I haven't gigged it yet or played it at higher volumes but I do notice it's a little leaner in the low frequencies compared to my other rigs. I play some dub style stuff that requires a lot of low end, will I be disappointed, should I put an eq in the loop and boost some low end?
