There seems to be a bulge around the end of the pegs that keeps them from seating well, but if you CAREFULLY shave that off with a good sharp knife and sand it so that it's rather rough the peg will be more manageable (worked for ME, anyway.)

Thankfully the pegs work just fine for tuning with a little peg compound on them

I had no trouble (beyond what one would expect from any peg tuned instrument with new strings) getting it to tune up, and the rosin worked fine with the bow for me.

The electronics work great, it sounds good even when not turned on

The free bonus amp cable they gave you works just fine for this
