hi zbasstringer,
my experience is that its absolutly ok to take todays corean models as a base.
there is career, uunsung and their brands, silver star...... they make good basses.
when you take a good PU and a cool bridge you shouldnt have any problem to make it a good bass.
my advice would be to test the bass without connecting it to an amp.
most of the times i even dont take the basses of the wall , or out of the stand:
just pluck the open a- string or others. when it's sounding alive and ringing, you have a good base. compare the dry sound with other instruments in the shop. sometimes the cheap basses have more resonance than expensive ones.....
a bass that is happening dry will not disapoint you........ hwen you add good extra features.
p.e.: i own a super cheap -justin- chinese pj bass, that was just cool sounding resonnant and dynamic. i payed 99 eur for it (ca. 140 $).
i put on a pj bass lines vintage PU combination. its a real coll bass now.
i use it in the studio an especially in rehearsals, because its light as a feather; and that make carriying around so nice. the sound is dirty and warm, cool for rock but when you ad more j- pu , you can handle all styles up to jacko sounds.......
in the studio it is a real alternative and noone ever asked me it was cheaper than my alembics or music mans.
good luck
