recently got another acryllic guitar made by Samick, serial number 7060316, 2 HB with SC formfactor /double rail type in neck and middle position, a HB at the bridge, all black hardware, licenced floyd rose vibrato, sharktooth inlays, 1 volume, 2 tone controlls, 5 position switch.
The only near relative I could find in the net was the KR 660 AC, but it has golden hardware, different inlays and pickups branded with Samick.
Any idea, what model mine could be?
