So this weekend I stop into my favorite local vintage music shop and spot a Mesa Boogie Bass 400+ for sale. I immediately ran over to check it out and it was mint. No scratches, never been mounted in a rack (no rack rash), just very clean. I talked to one of the sales guys there and they said they got it from one of their "regulars" that is a high-end collector. The previous owner bought it ten years ago and never gigged with it.....it was just used in his studio. After taking it for a short test run, I had to have it. It was just too good to pass up....it was in "like new" condition and I've always wanted one and they just dont show up for sale (especially in this condition) too often. I got it for a great price. Now, I plan on gigging with it and obviously want to put it in a rack case. I'm concerned with the fact that the fan for the amp is on the side as are the ventilation slots. I remember seeing a rack case years ago that had slats in it or something to that extent to accomodate the cooling system of this amp, but have been unable to find anything like what I remember seeing. Maybe it was a custom made case, I don't remember. Any suggestions or opinions on what to use for a rack case would be greatly appreciated. I can't wait to start rockin' with this head! Cheers!
