I bought this as a basis for modification - I plan to add an extra pickup for the low E and A strings with a separate output to go via an octaver into a bass amp. As such I know I'm going to replace much of the electronics, but straight out of the box, with a little tune-up, I was impressed with how well it plays and the sounds it makes. I previously bought one of the SC kits and the pickups supplied in that were terrible - these on the other hand actually sound pretty good!
The instrument is nicely finished, with no flaws I could see. The neck is nice, and the frets are well fitted with no sharp corners. The fret tops are a little rough though, meaning bends sound a little graunchy. Nothing a little polish won't fix though!
Tuners work well and it seems to stay in tune, and initial set-up is nice and low, although the intonation needs tweaking at the bridge.
The only real complaint is the bridge/tail-piece doesn't seem to be earthed properly, so it's quite noisy if you're not touching a string. As I'm going to be stripping it and rebuilding then I'll fix that along the way, but it's a shame when everything else was so good!
