i own of the SX bass guitars. it is quite good, and as not as super entry-level as a, say, TGM. i'd like to mod the SX i have now, but worried that my itchy hands might just ruin something. nevertheless, at the end of the day, the SX does what it is supposed to do.
and yah, i saw on harmony-central or somewhere, the ang mohs rate SX guitars and basses very highly..
As a SX bass player myself, I will say that SX is quite a good bass. If you use it with the amp they give, you will say it suck. But once you bought a better amp, like me, I use Ibanez SW35 amp, my thought really changed about the bass. It sound much better and I'm loving it.
i bought an sx p bass on impulse last yr and changed the split p to emgs. the sound was power. it's a really good entry level bass esp. if u r just trying out as a bassist....and may return to guitar, keyboard etc.
the only complain was the burs on the fretboard - just nid to file them down. also the pickguard had 2 sets of screw marks - ie. the template for drilling was inaccurate - not really bad cos it's hidden by the pickguard. soldering on the original was loose but nothing i can't fix. i really like the glossy finish on the neck reminds me of the mij fender strat i had with the same finish.
