I disagree with you.
You can't have box and put good guitar strings and expect the guitar player to play well.
Just like you cannot have a world class chef put mustard on a shit sandwich and expect it to taste better.
Yes, a good shooter can hit his target with a water gun but he is not going to kill what he is aiming for.
Cues play a big part in how you play but only from a certain price range. As you get higher in the price range the difference is miniscule unless we're regarding looks, as I mentioned earlier.
I have taken a wooden box, a 2x4 and a few nails....strung it up with 4 guitar strings, and made some very nice slide music using a cut piece of copper pipe....
I have to disagree with you.......
