same conundrum here. i was able to play the SUB Ray5 (used) locally and did like the way it felt. i was a little worried about the threads i've seen here about the hot preamp output in the SUB and how some feel it's clipping their amps inputs and distorting in a bad way. i played it through an SVT-CL and ampeg 8x10 that was there also and it did sound good but you could really get a MUCH louder sound out of it when rolling up the bass knob and with the volume all the way up on the bass. it was far louder than any of the other basses i played through the same setup (fender jazz, ibanez hollowbody 5'er) with the same volume controls. didn't seem to distort the input of the SVT-CL though...
i ended up ordering a squier VM P5 in olympic white which should be here end of the week. ultimately, the SUB just isn't what i'm looking for, even though the used price was nice.
Note to self:
Humility, Sorrow, Gentleness, Justice, Mercy, Purity, Peace and Sufferance
These are worth contemplation.
