Roger glad to see you have your 600 in a case similar to mine or mine to yours. Got mine kinda cheap online, hard plastic says CNB on front cover. So, I was reading some threads here recently on how adamant folks are about leaving room for their amp fans. There's maybe an inch or more from the side of my case to the amp. On my GK I have it with a BBE Maximizer on top in one SKB case, maybe 1/2 to 3/4 inch of space above that fan. But Ive played both these amps even outdoors in hot, humid, Houston in July-August, in the open sunlight, never had a problem with either but it was always in the back of my mind. Plus I would just turn the GB fan to hi. Oh and if you read this, thanks for the tip to find the Neox 212T, they were cool to reply to me with a decent price but I actaully found one locally for abit less $$. Im gonna use the 212 w/GBE600 at a club gig this Friday nite. Looking forward to opening her up to see how she runs. Will try to post some pics soon.
