I've decided to go for it. I'm building a replica of Doubleneck de Poitrine. I've bought a 40€ #guitar and a 50€ #bass, laid out a rough shape and I'm gonna buy some #tonewood in a local hardware store now. It's a 17€ spruce plank, which I cut in three pieces and glue side by side to get the width. I haven't decided on a couple of things yet. Firstly, I'm not sure if I want to reshape the headstocks to match the original #AngineDePoitrine instrument. I may even make it different on purpose. Secondly, do I refret the necks completely with identical frets, or do I buy the tiniest fretwire I can find, so that I can easily see where the standard notes and where the quarter-tones are. Again, depends on my decision to make an exact replica or not. I'm leaning towards making it my own.
