Feature:
Works as expected. Ultrabass... don't care really since got an octaver on my GT-6B. There is a audible pop when turning on the Ultrabass. Shape is nice; it's like a sweepable notch filter. Comes with a foot pedal that can switch the Ultrabass and Shape on/off (haven't used it yet)
Quality:
Solid, feels well put together. Used it in several outside gigs where the temps were well into the 90's and the unit in direct sun. NO troubles.
Value:
Nice features and great price. $450 for this head and a 210 cab... Wow!
Desirability:
Looks nice. Maybe a little spartan compared to some, definately looks cooler that my 800RB did.
Sound:
Hard to give it a 10. I needed an inexpensive rig to replace my ailing Ampeg 115 and decided to go component again. Had a GK800RB and PV1820 forever before the Ampeg. Teamed with a BB210 Cab and sounds great. If you really want it to scream you need to run it @ 4 ohms though. Figure I'll get a BB115 to go with it eventually.
Ease of Use:
Gain structure is a little weird but easy to get used to. For whatever reason I haven't found the input meter to be terribly useful.
Support:
No clue. Haven't had to.
Overall:
Rolled the dice.. bought it on price and reviews. Was pleased that I didn't have to send it back. In the future I may cross over to using a straight power amp like the EP1500 with the Behringer cab(s), since I could do most of the preamp stuff in the GT-6B.
