It's impossible to say whether it will be comfortable or not, that depends on the size of the person(s) sitting there. A guy who is two meters tall might find it uncomfortable, someone who is 1.70 meters tall might find it ok.
Since you probably will be the guy who uses the cab the most, it should be comfy for you.
Do a simple test : Grab something that is 75 cm high (a table, some cardboard boxes, a stack of books, whatever), put your chair in front of it, yourself in the chair and pretend to play.
Is it comfy ? Cool. If not, you can a) use an adjustable chair or b) change the height of the control panel.
