Well, I guess you might have wanted something called a "variable radius fillet" in that case which is a type of fillet that has a radius that gradually changes from one particular radius to another radius value as the fillet travels along. MoI does not have that kind of filleting set up in it yet.

So you will probably want to create a similar kind of surface manually, something like this:

Start by selecting these faces here (there's also a little planar shelf like piece in there as well):



And then just hit Delete to remove them, leaving an empty hole there. Now you have some space to work with to fill in by constructing a surface that has the kind of transition that you want. You could draw in some guide rails and do a sweep, but actually the easiest is probably to use the Blend command. Select these 2 edges here:



And then run Construct > Blend - that will build a surface that connects smoothly between them, making this result:



Now the problem is the surrounding surfaces are not the right shape to match up with this new piece, so those have to be reconstructed as well.

Select these 2 adjacent faces now:



And delete those too, leaving a big hole above the blend and on the bottom:



These are both planar holes so they are easy to fill in though - to fill them in select the blend and the main guitar body and use the Edit > Join command to glue them together to be connected.

After you do that, you have 2 planar holes you want to fill in which the Construct > Planar command can do for you - just select the object and run Construct > Planar and it will create planar faces and join them in to make the guitar a solid again.

Let me know if you get stuck on any of these steps.
