I wanted to know if there were any negative tonal/resonant effects from bass guitars using this type of headstock design. Is it much harder to do quick broken string changes? Is there much of a reduction in vibration from the missing wood? Is it nothing to be concerned about, period? I like the looks on the new Bollings, Grs, some EUBs, etc. Whaddya think? There IS a supposed advantage to the greater string angle from the nut to the tuners but I'm dubious about it's effects "north" of the nut. Are the downward facing tuner knobs any problem in use? Thanks.
