The lines are because “phenowood” is made of many thin layers of wood sandwiched together with phenolic resin, somewhat like Micarta but much coarserThanks for the reply! I am really puzzled about the hum/noise that you both mention. I wonder if JZ has done something about the electronics... I just listened to the bass through headphones and there is literally no noise at all (or my middleaged ears are just fooling me - also a possibility...).
Could you upload a pic of the lines? I would be very curious to see other examples of this. Any idea why that happens?
I'll upload clips shortly!
then when it’s shaped, the wood layers are more or less visible depending on shaping depth
