I'm looking to swap out the dual coils in my SKB 5 for some singles. My dilemma: Roscoe's use of six string-sized housings on their fiver's has ruled out my first choice, Aguilar Super Singles, since Aguilar doesn't do custom orders. So, I think my next options are either Nordy Jazz Bars or Bart Singularities. There doesn't seem to be much in the way of sound clips for either of these available. Does anyone have experience out there with either of these? Thanks for the help.
