I think the thing is folks here need to know why, need some context. Do you want tabs as a teaching tool, maybe to provide students, or do you want them for your own learning of songs? If the latter, then IMO, that's an unnecessary "middle man" step. You get the tabs, then you have to read them to learn the song. Too much work. I cant speak for everyone but despite the fact that I read both "music" (notes) and tab, I never do it for learning songs. I use my ear. For complex stuff I'll make little scribbled notes here and there, but never an actual tab. Others' mileage surely varies, I just never found much need for bass tabs. Tell us more about your needs.
I need bass tabs for 2 easy songs: 1. Bruce Springsteen- No Surrender 2. Bruce Springsteen - Roll of the Dice Unfortunately, I don’t have time for creating tabs myself, that’s why I’m asking and ready to pay for it.
