yes,i dont see many tube
mods using the onboard buttons,but on the other hand I see many box
mods using the one central button and the ''wired buttons''.I suppose the best should be one board for two cases.In one case for the tube mods there should be one central button with no other buttons onboard, and a menu with one button(the
dna 20d has a very nice screen with a lot of indications,so it would not be hard to navigate to the menu) and for the box mods as we know it now,one central button and two wired buttons.your opinion?
