I visited Nik and his operation a few months back while gigging in KL... cool dude, & a bunch of down to earth guys working for him - very tidy and organised all up. Played through an overtone special that had just been wired up - great sounding, tho not my cup of tea - but its his biggest seller at the moment and the guys are snowed under trying to get those orders out. Had a Ceriatone Proluxe (6L6-powered 5E3) a while back that I shouldn't have sold.
Can't go wrong with Nik.
Btw, from the man himself, the correct pronounciation is "cher-ee-ah" tone - deriving from the malay word meaning bright/sunny/happy
