I am thinking of adding one to my beloved jazz bass. Thing is, unless I just buy one, I wont know what they are like to play with. I have tried a vintage jazz with one on but the whole bass felt alien and I could not be sure unless I order one and secure it with Blue-Tac (TM) temporarily, before screwing. (Scerwing it onto my bass you filthy lot). So what do y'all think of 'em? Will i still be able to play pinch harmonics (touching vibrating string with side of right hand momentailrly to sound harmonic - I usually do this just over the front pickup)? Thanks for your comments which continually inspire and provoke the spending of cash!
