I bought one of these at a U.S. retailer as a open box item. Loved the sounds I achieved with this head, but unfortunately it died after about 1.5 years of use. Power section basically crapped out completely. Trying to find someone to fix it, but GK customer service has been a joke. They simply will not answer emails, which is a common thing from GK from what I've been told from other bassists I've spoken to. I will stay away from anything GK in the future. A buddy of mine had a similar issue with them 15 years ago, and it looks like they haven't gotten any better in the customer support area. Great sounding gear that won't last. Waste of money.

NOW AFTER TWENTY YEARS OF TUBE TO SOLID STATE AMP USAGE I CAN SAY "WHO'D HAVE THOUGHT THE WARMEST TONE I'D COME ACROSS WOULD COME FROM A HYBRED". GK RESPONDS TO VERY THING I DO. GREAT TONE,GREAT WARMTH. GLAD I CHECKED IT OUT, I'M SOLD.

I've owned for over a year now. Played many a gig with no problems. Fantastic tone, super portable, great controls that really work. The only draw back is that it is not a truly 2 channel amp, because they share the EQ settings.

I Bought this a year and a half ago and it is still going strong. Beautiful tube tone and weighs nothing. Tons of tone adjustment and two channels. The only drawback or benefit I found is the B channel (dirty) is very dirty. I starts distorting very quickly and goes to a really cool fuzz if you like that sort of thing.
