Is your guitar a Dreadnought and are you of smaller stature? Is your guitar [u]a comfortable physical fit[/u] when you're sitting?

I play sitting without a strap all the time, with no need to wrestle with the neck nor is it an encumbrance fretting. Strats, Teles, double cuts (Revstar), Concert acoustics. [br][br]Two guitar [u]types[/u] I can't enjoy sitting, one without use of a strap. Les Paul electrics, and Dreadnought acoustics. The Les Paul body is bottom heavy, which in conjunction with the body shape isn't conducive to balancing and sitting on the thigh. They slip off, and the neck will want to rise and pull away. They're neck wrestlers, which will interfere with fretting. [br][br]Similarly Dreadnoughts. All that body bulk is just a rubbish physical fit [u]with me[/u], and situating it so I can physically manage it locates the neck uncomfortably further way than with a Concert body. A strap resolves the Les Paul issue, but not the Dreadnought issue.
