> Give me my previous/next physical buttons back. That's not a guarantee of anything. For example, the BOSS Katana line of digital amplifiers has physical knobs. Of course, the knobs are digital rotary encoders. But do they have a display like most? No. So you have no idea of what you dialed in at a glance. It's easier to connect your phone through the USB port to the amplifier and manipulate everything through the app. It's appalling.
