great if you like fluffy, woofy, UNCONTROLLABLE bottom end...the passive radiator can be a royal PITA in a bad room, and NO amount of eq will stop it - it just booms out sub sonic rumble all the ****ing time. Also, the amp itself has very little headroom for the wattage claimed...just don't like those things. That head sounds infinitely better with the Mesa single 12 Neo cab; then you're onto something. Or better yet get two of them. Much better than the Scout. And if you want to hear what they REALLY sound like without the fake passive radiator pumping BS into the room, pick one up sometime and play it off the floor - honky, boxy, NO bottom end...horrible things. People are bedazzled too easily by that stuff. And yes, I've played them at gigs and rehearsals, several of my students had them YEARS ago when they first came out, and everybody sold them, eventually.
So many know it-alls-claiming this is the greatest amp ever, I just had to intervene...they're OK, but I like the Markbass MUCH better. And for about the same price as the GK (which is nasal and very boxy, requires a TON of EQ to get a bass sound out of, and there goes all your headroom and dynamic range when you do that), look at the TC 250 combo for about $400.00. I was JUST AB'ing the GK 12 (which was within $20.00 of the price) and the TC a few hours ago by coincidence - TC won by a knockout.
But the Markbass has WAY more power than ANY of these, and is way more flexible and with tons more headroom - another class of amp completely.
And IMHO, the best 12" combo EVER made is the Berg IP, which will totally annihilate ANY of these amps.
Walkabout Scout...$1500.00...no thanks. You could buy a MASSIVE used rig for that price, and some really nice stuff.
Cheers,
