If it's not a surprise, I would ask the husband some questions. If he plays classical guitar, does he want the foot stool/step attached or separate? Some stools have a built in foot rest.
Also, how tall is he and how high would he like the seat to be? If you are going to make it height adjustable, that may not matter, but if not, and he's not between 5'7" and 6'1" or so, it's probably worth talking to the player.
Just my initial thoughts on what I'd ask my friend Mike who plays classical guitar, acoustic, and electric.
If it's a surprise, tell me how tall the guy is, and what type of playing he does, and I'll ask Mike.
Sorry I can't help more,

Mike,
Here is a picture of Tage Frid's three-legged stool. It is from his Tage Frid Teaches Woodworking Book 3: Furnituremaking. I was really impressed with how stable it looked in the DVD that came with the book set. The seat is 22" high and the back is 30 1/4. The handle may also be a good design feature for a guitarist.
Mike, just out of curiosity I went Googlin' and ran across this. Very unique, doubles as a stand and stool.
It's made by this company Paparwark Furniture
But I bet we could figure out how to make it at home :icon_thum

Mike,
Check out the chair I posted as "Be careful what you ask for". My cousin loves it. He's 6'3" and plays acoustic and electric guitar. The back wraps around so you can prop your arm on it.
