I have a Crate V18 212 combo cab that I think would work with the 36watt combo chassis, if of course the numbers match a little.

I thought about ordering both the Head and Combo chassis but that's just too much for right now.

The control opening is 18"x2 1/4" , There's 7" of clearance behind the chassis, should be plenty forany Tranny hieght and the tubes would be hangin' of course.
Width of the entire cab is 27"

What are the specs of the 36watt chassis?

Thanks
