Why is it that Guitar action can be lowered alot more than on ukes? I seen some guitars that can be lowered to 1/32". Is it because ukes don't have relief set on the necks? Through my research, I see that Mya-moe ukes are built with relief but seen posts that say relief is not neccessary in ukes as the tension is not as great. And if this is so, what brands of ukes has relief set in them that are priced under $500?
