i've got one. it's the best SG type guitar i've ever played, including any gibsons or any other copies or guitars of the same type
it's the guitar i still use the most . ive had it longer than all my other guitars, and everytime i go to pick one up, i always go for the tokai first.
it has a really thick neck though, i don't know if that would suit you but it feels really nice. it has really good top end access.
build quality is very good, i've never had any problems with the electronics, or any other components. the only thing was the pup selector crackled after a while, but sliding a fine piece of sand paper between the contacts does the trick.
the tone of the stock pups is actually suprisingly good compared to some of whats out there. a good full tone but lacking in mids on the neck pup in my opinion.
the bridge is ok,plenty of bass and mids. nothing on the abraxas i've got in it nowadays though. it sounds fantastic now, the BKP cuts through much better for solos.
i've played the hell out of it for four years now and only just startin to think about a fret dress.
hope that helps.
matt.
