| I am of the opinion that construction has more to do with sustain than wood selection. I've never had a sustain problem and I have used wenge, maple, sapele, jatobah, picana negra, bubinga, and others. I'd also add that either bubinga or maple will work well as stringers, but my personal preference is bubinga because I prefer to have similar textures and similar movement properties between the laminates at this point. |
