The largest of the fret sizes, jumbo frets are tall and wide, which lets you get a better grip on the strings, enabling more control over them and making bends and vibrato easier. A good choice for players with larger hands and thicker fingers.

Single-coil Texas Special pickups are over-wound for big Texas-blues tone with dynamically scorching output. With alnico 5 magnets, enamel-coated magnet wire and staggered pole pieces for balanced output across each string, they sing, scream and everything in between with tight bass, focused midrange and crystalline highs.
Surely the most distinctive visual element of this instrument is its black pickguard, engraved with the big, bold initials of the man himself.
