The WI24 was made between 2002 and 2003

Originally introduced in 1999, the WI64 was the very first Idol model. With its bold single cutaway style and dual humbucker layout, the Original Idol provided a great alternative to the standard Les Paul clones. The WI64 has Washburns Voice Contour Control (VCC) circuit. The VCC circuit changes the tone of the pickup by blending coils rather than using the standard filter this varies the WB 600 series humbucker pickups from full humbucking mode to coil tapped mode and every tonal color in between. Go from thick crunchy tones to near single coil pristine tones by just rotating the knob.

Introduced in 1999 the Washburn WI64DL was the deluxe version of the WI64 Washburn Idol model. Its deluxe appointments included a quilt maple top, transparent finish and gold hardware (I think Washburn should have also included block inlays but nevermind). Features: Mahogany body, quilt maple top, 24.75 scale, 22 frets, Washburn 800-series humbuckers, one piece mahogany set neck, 14" fingerboard radius, Voice Contour Control (variable coil tap), 3 way selector switch, Grover tuners, Buzz Feiten Tuning System, Tune-o-matic bridge.
