Thanks guys, you are very helpful. Summer in northern Germany is always good for a surprise, you never know what you'll get. The last two years, it was pretty damn hot (30+ degrees Celsius) and little humidity, but I also remember 20°C and rain from March to November...
What is the best way to let the guitar finish cure? Assembled and standing on a stand, or assembled and resting in a case? Or in parts and - at best - hanging suspended with no touching point, or at least hanging from a wall mount? I have the neck hanging from the living room lamp (at least it looks decorative) but I'm not sure my husband would fancy the idea of keeping it this way for a month. Just asking because it would be sad if the tru oil would get pressure marks....
