Mapleshade or Butcher Block Acoustics

I own both, 3" thick maple from Mapleshade and Butcher Block Acoustic. They are both excellent and I cannot hear a difference between the two products. I’d suggest you purchase whichever one is more pleasing to your eyes or within your price range. Honestly, you can’t go wrong they are both excellent.
Butcher Block Acoustic has a greater selection of options.

No one should want one solid piece of wood because it will warp. That's why builders use amended wood etc.
