This is a new electric guitar that I have seen her playing live. It's a G&L Silver Flake finishes telecaster/hellecaster. I know she is holding a signature series but i can't just identify it. Maybe if I have the chance to meet up with Cheer I can ask for more details !
Just got confirmation: this is a Limited Edition (one of est. 190 in production) G&L 1995 ASAT John Jorgenson model! Resale price now around US$2500
Btw, the guitar has almost a matching type silverish metal flake finishes as her boyfriend/producer/lead guitarist, Tiger Chung.
