After reading the tutorial several times I think I got my head around it, excellent tutorial. I Posted my question in the Eof thread and it was suggested I check this tutorial out which I did, but I don't think that the tutorial answers it.
I hope I'm not sounding dumb but bends, prebends and their many variations raise the pitch of the note by 1/4,1/2 ,1 etc. why I want to do is to actually bring the pitch of the note down to, -2 or -21/2 on the low E string which wl bring the E note down to C then back to the E.The song is Jailbreak by AC/DC and Angus Young does it by detuning the E string with the Tuning peg. You could use the tremolo bar to do this and I would like to put a negative number in to reflect this dropping E note but I don't think I can. I hope this makes sense and I hope I'm wrong.
Thanks
