I have a boss Tu-2 tuner. My band tunes a hlaf step down or one flat. I usually set the tuner to bass one flat. No problem with that. ......but when I tune it shows the string number. ex 1=g 2=d etc. But what do I do when I use a "drop D" tunning?? I thought about setting it at chromatic, but it doesnt account for the half step tunning. Am I missing something?? Help!!
