Hey Jagstang
I got my hands on a Jaguar HH Special Edition last year. I saw the colored headstock, HH configuration, tune-o-matic, etc, and after reading some reviews/doing some homework on specs, I snagged it. I enjoy it a lot. I slapped some strap locks and new tuning knobs on it and its great.

Anyway, I am thinking of saving some money up and ugrading a little bit. I have a few questions for other Jaguar HH owners and I'm hoping this is the place to get my questions answered. Any help you can provide me is greatly appreciated.
Forgive my ignorance, I am a newb.
1.)Hard case - I need a hardcase for this guitar. So far reading online reviews/message board posts has got me no where as the same items that state the guitar fits perfectly also have reviews detailing the problems of using this case with that guitar. So my first question is, what is the best fitting case for this instrument? Jazzmaster case? Jaguar case? Which brand?
2.)Pickguard - I am considering changing the pickguard. Havent decided what color yet. Anyhoo, what reputable dealer can provide me with the perfect fitting pickguard? I dont want an ill-fitting ebay cheapo (been there, done that). Are pickguards hard to swap out on this instrument?
3.)Pickups - I am also tossing around the idea of upgrading the pickups. Problem is, I know nothing about upgrading pickups. I have yet to pick out what I want but I need to know, given the amount of switches on this guitar, are pickup replacements especially difficult? I would love to improve the sound of this guitar but i have no idea where to start.
4.)Cleaning - What cleaning steps do you recommend to extend the life of this guitar? I have read about lemon oil - both good and bad things. I am considering buying some name brand guitar neck oil but am weary of its price/effectiveness. What do other owners of this guitar here do? Clean after every use? Wipe down strings? Clean fretboard? How?
I think thats about it. Ill update as necessary. Thanks guys!
