Anyone here old enough to remember when we had no electronic tuners? Many bands I played in had no keyboard, organ, piano, etc for reference, so it could be a 10-30 minute ordeal to get everyone tuned. I still have dreams where I'm telling the bass player "Gimme a low E"! This was our first electronic, a Peterson T-100, bought from Rhythm City in Atlanta about 1977. It was a real game changer, best thing ever as far as I could tell. I still have it, and it still works.
