well, but this is like giving away a million dollar idea:
Stratocaster jack inputs suck ! ( the angled ones on the front )
They get unscrewed and are hard to tighten (without breaking the cables behind them). There are systems in which the input can't get loose,. because it's all one part, which is expensive to replace. But the placing is great and you never miss the input, you can still put your guitar on a stand without the jack touching the ground. Improve on the "front angled input" !
From a designer point of view, get rid of ugly headstocks !
Overall, the guitar is a pretty wel designed and developed product..
Good luck !
Fix it !
