I own Kz One Standard (Semi Hollow body, all mahogany, Kahler tremolo, tri-sonic PUs with series-parallel swtich).  This guitar is a sort of upgraded version of Red Special, but has many unique features.  For example, Kz One can have four out-of-phase sound patterns - more than Red Special.  Pattern one : neck+middle out of phase series, Pattern two : neck+middle out of phase parallel, Pattern three : neck+bridge out of phase series, Pattern four : neck+bridge out of phase parallel. 

Interestingly, the Pattern four is most suitable for Bohemian Rhapsody solo.  Pattern three and four can enjoy noise-less squeaky sound and what I have found is Parallel out-of-phase sound is squeakier than Series out-of-phase sound.  Pattern one and two are suitable for solo play around 12-15 frets - great for the song "Dragon Attack". 

Because Kz One PUs are installed differently from Red Special (more distance from the bridge and 22 frets), it can have unique sound with more variety from its series-parallel switch.) 

Kz One is really easy to play with extensive care for quality and suitable for variety of music including not only Rock music, but Jazz and Progressive Rock.  Highly recommended.
