wow, thank you all so much for the replies, you've helped me reach my decision: sell this one and buy a different one. i don't really have the time or experience to refinish this one (let alone buy beater guitars to practice on!). and if it'll cost $500-600 in the US to professionally refinish it, who knows what it'd cost here!!! for that price i should just buy another one! (i asked one more question at the bottom of this post...)
and to respond to some of the comments/remarks:
i don't think they have the saying "if it ain't broke, don't fix it" here. in fact, it seems they might have the opposite one--if it ain't broke, FIX IT!!! they're always tearing down some 'old' building (20-25 years old) and constructing a new one in it's place, renovating renovations and trashing perfectly good cars (15 years old and less that, by american standards at least, are sound and roadworthy)!
yeah, the wood underneath might not be perfect. when i look at the top at certain angles it seems there are some dark spots or areas that seem a little uneven.
the prices of guilds--actually anything american made and vintage--are high here. and they are somewhat hard to find, so even higher. i actually had this guitar sent from the US, and it was still cheaper than it would have been here--that is if i could even find a D25! (i saw a pretty beat up D4 here at a guitar store, and they were asking close to a grand for it) the good thing is that right now the yen is strong/usd weak, so i can buy the guitar in the US and have it sent here. and japan doesn't have a duty tax on musical instruments, or sales tax on used items (though new items they'll hit you up for 5% of the cost). i should be able to sell mine for what i paid for it after shipping--hopefully....
as for keeping this one and getting another guitar (such as a jumbo, etc), i really can't behave in such a way, haha! actually, i'm a drummer first, but have always made songs, and so now i'm trying to get into singer/songwriter stuff more (since it's hard to play drums here). and besides the fact that i can't afford more than one guitar, the size of my "mansion" (as they call it) won't allow it either. (just think an airplane-sized bathroom, dorm room fridge, washing machine and sink crammed into a space that is the size of a small bedroom.... that's my apartment! though it comes with regular sized rent....)
now, one more question. being that i'm not that familiar with guitars, how difficult is it to swap out the piezo pickup in my guitar to the new one if/when i get it? and is it possible to put the original strap pin back in where the pickup has been removed? i've read the hole has to be enlarged when installing the pickup....
oh, and i'll try to post some pics, as soon as i figure out how!!!
thanks again, y'all! great to be here in the friendly knowledge pool even though i'm across a big ocean!!!
