I'm pretty sure that this is posted in the right forum but if its not I'm sure one of our friendly neighborhood mods will come along and point it in the right direction. Here's my dilemma, I am jsut new to detuning and currently I am learning material that requires tuning down 1/2 step and one whole step on only one or multiple strings. I am just wondering if there is any special adjustment that should be made to my bass before doing this. I am currently playing a Jazz Bass 24 and Geddy Lee. My main worry is with the Geddy Lee cause of its very thin neck. At the moment I am practicing all the detuned songs on my old Samick P-bass copy that already plays horrible anyway. Just want to get some input before I take the plunge on my main axes.
