Can't believe it...forgot my tuner. Didn't need upright or effects so I left the pedalboard at home with the tuner on it and forgot to get my pocket tuner. Man, was I lost! I couldn't tune my bass all night and I just had to guess, and I was so far out of tune that the headlining acts were completely thrown for singing, and the gig was a total disaster and everybody was mad at me. And then we had the second show, and a total repeat of the first show happened. Not really... Actually I got a pitch from the piano and tuned by ear before the audience got there. I was dead-on all night, and even caught it when a string occasionally drifted slightly. If I hadn't screamed "I forgot my ******* tuner," nobody would have known. I understand that there are a lot of folks who play an instrument who don't know how to tune it without a tuner. One day you will forget your tuner, too. Learn how to tune your dang bass by ear or everyone WILL be mad at you...trust me.
