GK 400RB-IV... Are there 2 versions ???

Was looking into picking up one of these used. I've noticed that on some of these the fan opening is larger than others. Are there 2 versions of the RB-IV? Is there any other differences between the amps besides the larger fan opening?

Hi bluesrx,
The 400RBIV is my main amp.As far as I know there was only 1 version. Although Gk does change their cosmetics now and again. just ask the guys with mismatched grill covers on their GK cabs! I've seen quite a few and never noticed any difference in the fan openings. Then again i wasn't looking for it. Great amp though. Sorry I couldn't help more.
