I really don't know which one to choose. The new roasted maple ones have received really good notes on Basstheworld youtube channel. I don't like the finish on them though, I much prefer the natural look of the old B4. Does the roasted maple fingerboard and panga panga/walnut neck really make such a difference over the maple/wenge neck with panga panga fretboard? Has anyone here had a chance to play both versions?
