Hey wvbass
I hate to keep repeating myself - it's nothing but a big yawn for most - I realize - but my only experience with full scale basses was my 1972 Fender Jazz - with apologies to those who have heard this many times before - but the SERIOUS dead spots were from frets 4-7 on both the D and G Strings. I thought Fender was sending all the "seconds" to the GI's overseas - and maybe they were. But 8 notes suffering from ridiculously premature decay was too much to bear - and I know this sounds harsh, but the truth is NONE of those eight notes would sustain for more than a second. Do you hear me? EIGHT virtually unusable notes. Yeah, show me the "work-around". Do you blame me for being a such an intense anti dead-spot advocate?
Once I got back to the states, I sold it - never to turn back. Will never own another Fender long scale again under any circumstances. Lesson learned. I want to be sure everyone is clear - for me - any note that will not sustain for a least a solid four count - at a slow ballad tempo - I consider a dead spot. If it is ok with that test for me - and sustains nicely - I could care less about ghost notes and specifically which notes sustain more than others. No need to rain on my parade, if I can get a four count at ballad tempo an on each and every fret - I am smiling big time - and good to go. No reason to analyze any further.

From your description of your 1972 Fender Jazz it sounds quite obvious that the problem was not one with dead spots but something far more severe. Basses can only have one true dead spot as a bass neck only has one resonant frequency. I don't doubt that your bass had those problems, I also am pretty sure that somewhere on the G string there would be one true dead spot. It also seems pretty clear from your experience that medium scale basses do curb the dead spot problem. But with all due respect... 8 dead notes? A one piece neck with 8 resonant frequencies? No. The problems you describe have nothing to do with the bass having a 34 inch scale.
Whaddya know? Seems I am NOT the only one after all.
