Hey all, first time long time. I've owned the jagstang long enough to know that before its ever going to be of notable value in the long years to come,,,it needs to be played in the meantime, ahem,,,which also means its needs to be modified! So i'm going Duncan JB in bridge first. My question is which one, sh-4 or tb-4? anyone know which kurt used? I hear the trembucker (tb) is for floating trems which these guitars have, but is that what i should buy? is there a difference other than pole spacing? Curious on thoughts on other must do mods, thanks guys, really appreciate your help.
