I can pitch in here. I have a custom Lion from Jon and its just simply an amazing guitar.
Nowhere else could I get a Les Paul style korina body, with bolt on 25.5 scale maple neck and ebony board with MIDI, body contours, quilt veneer coloured for my personal preference and neck profile copied from my fave Washburn N4.
Plays amazingly easily, sounds awesome, looks superb and there's only 1 in the world ;-)
