I hope no one rags on me for wanting to use a tuner, but i need to work on tuning by ear and ia m, but id still like an electric tuner espeically for shows since my ear is not as perfect as id like. What i am looking for in a tuner is a tuner that can basically tune any string to a variety of notes. Example if i want to use B tuning on the Bass, B-E-A-D, i have the option to select the B note, and tune my E string to B. Or in drop d, i can select D, and tune my E string until it picks up the D pitch. is there a tuner out there that does all this? I will learn to eventually do all this by ear, but the new band im playing in is going to be using a lot of tunings and i dont want to look like a doofus asking them to help me with the tunings and or help me learn them. thanks.
