I have the SV5470 in the blue finish. Great guitar. Neck carve is not the same as the rest of the prestige series. It's a bit thicker neck. The S5470 has the classic Prestige Super Wizard shaped neck.
The trem isnt all that great for staying in tune unless you get a proper setup for the string gauge you play, nut lube, etc. But it isnt bad for basic vibrato.
Guitar plays fantastic though and I would have a whole rack of them if I had the dough.
The pickup system is interesting as well. Its not standard coil tap on the volume knob. Its the True Duo Blast system. It's essentially a humbucker with a stacked single coil for one of the coils. This way you can have a full humbucker sound as well as getting a single coil tone without hum.
I swapped the pups for Evos in the neck and bridge, but kept the coil tap. I still have the pups if I want to put them back in.
