Hi all, appreciate if somebody can gimme some advice on the below issues; 1. I'm thinking of buying a Warwick Rockbass 5-string (China-made) but was told that the wood of Warwick basses are only suitable for US and European weather climate and not suitable for Asia and Singapore (where I'm from) climate as it will cause the wood to warp alot in the long run... is there any truths to it? 2. How do I prevent my bass necks from warping? This is a problem that I have been facing ever since I've been playing bass. Besides adjusting the thrust-rod, is there any way to prevent it from warping? Thank you!
