The model shows us what you have, but not what you want. Could you sketch that ? (pencil, and paper still works fine 😉
You need to urgently work on your sketching technique. None of your sketches, particularly the one with the main profile is full constrained and dimensioned. That makes edits very dangerous.
Also, you should always in some form reference the sketch origin!
Nope, not really. You should not be able to drag any of the sketch element just by dragging it with a mouse.
I've attached a WIP file where the first 2 sketches are full constrained/dimensioned.
While you can loft in the sculpt environment in this case I'd use either the loft command in the Model or Patch environment.
Yes, that s correct. You can either start a sketch on a flat face of existing geometry, or on a construction plane. If you don't have a construction plane that serves the purpose the you need to create one.
I can verify from personal experience that modeling a guitar neck like this is a challenge (on both ends - the transition to the headstock is hard, as is the transition to the body). I would approach this by over-building the neck, and then using a surface to cut away the curved back. You might be able to just create a parametric loft surface as the trimming surface, but you might also want to use a TSpline (Sculpt) loft surface, to have more control. I will see if I can find time to give it a go, but I'm out of town for 2 weeks, so I can't promise I'll get to it.

My method for dealing with problems like this is to use the Surfacing and solid tools to nail down known shapes, then I convert the body neck and head into a set of T-Splines for correct curvature. The problem with doing it all in surfacing is your curvature will probably be garbage because of the lack of control in the surface environment. Too many people (not referring to you in this case) ignore T-Splines as an integral step to solving problems like these. These problems are exactly what T-Splines were designed to solve.
I will TRY to get some time to make you a video.

OK, here is how I spent my evening in India...
I made some progress here, trying to use traditional modeling tools. As mentioned above, this is a real challenge for me, and I've tried it a few times along the way.
Here is the visual result:
As I say in the screencast below, I'm not happy with what I had to do to get this to work, but I did make it work in the end. It's not probably the best workflow, but it might give you some ideas how to move your own version forward.
Here is a screencast:
Good luck with your design!

Your model illustrates exactly why I wouldn't use the current Patch or Solid tools to make this part. Curvature and Zebra stripes show the problem areas.

Your question is not lame at all. It is a completely valid one.
The head stock and neck would be part of the model I would do with either solids or surfaces. The trick is not to model the blends with surfacing or solid modeling, but rather do the blends in T-splines. I'm putting something together for you, hold tight. Here shows the difference in surface flow between the two methods.

The real question I have for you is do you want to learn how to model it with T-Splines or just how to fix bad curvature with T-Splines?
