I'm very guilty of the latter. I convince myself that I'm 'practicing guitar' but in reality, I'm just messing around with sounds, and sometimes checking out aspects of my overall tone - and planning the next pedal I'm going to spend hours and hours investigating on That Pedal Show or Youtube, and then eventually buy the thing. I LOVE watching that stuff. It's one of my favourite things, but I'm doing very little in the way of focused practice, and honing my chops into shape. Do you think there's ever a day where you think, "okay my rig and my sound is perfect" - and start getting on with the job at hand?
