The Q10 will accept LINE inputs... to me, this means one could use pricey preamps with the Q10 as line level devices.
To me, the Q10 is like an American series Fender Precision bass. Good sound, does the job well. No, it is not a Sadowsky, but it isn't as pricey, either.
One has to ask if they need more than an upper-middle of the road piece to do the job.
