The 2009 Paul Reed Smith Custom 24 10-Top is an exceptional instrument from a highly coveted era of PRS production. Several specific design features and historical milestones make this exact instrument stand out: [1, 2]1. The Legendary 57/08 Pickups These proprietary humbuckers are widely considered some of the best vintage-style pickups PRS has ever made.

• The Vintage Wire Story: In 2008, PRS acquired the exclusive rights to the actual 1950s-era wire-winding machines that created the legendary PAF pickups.
• Tonal Character: Wound in-house, the 57/08 pickups offer remarkable clarity, low-end warmth, and an uncompressed, vocal-like mid-range.
• Exclusivity: In 2009, these pickups could not be bought separately; they were reserved exclusively for high-end Private Stock and limited-run Core models.

2. The Golden Ratio Scale Length The Custom 24 utilizes a 25-inch scale length. This acts as the perfect middle ground between the two traditional electric guitar standards:

• It provides a tighter, snappier low-end than a Gibson's 24.75-inch scale length.
• It offers easier string bending and a warmer mid-range than a Fender's 25.5-inch scale length.

3. Iconic Bird Inlays The fretboard features the legendary PRS Outline Bird Inlays. The 24-fret model includes a specific, unique extra bird soaring on the highest fret that is not present on 22-fret models.

4. Flawless Ergonomics and Tuning Stability

• Straight String Pull: The iconic 3-on-a-side headstock design ensures that the strings travel in a perfectly straight line from the Graph Tech nut to the tuners, eliminating the friction that causes tuning instability.
• Patented Tremolo System: The unplated brass components inside the bridge block transfer acoustic resonance directly into the mahogany body, maximizing sustain.

The Paul Reed Smith Custom 24 featuring serial number 09 154185 is a premium, USA-made Core series electric guitar built in 2009. Factory Specification & Verification

• Production Year: The prefix 09 confirms it was manufactured in 2009.
• Production Sequence: The remaining digits (154185) fall perfectly within the official 2009 set-neck sequential range of 146420 to 159132.
• Wood Grading: The 10-Top designation means the carved flame maple top is of exceptional, near-flawless figure quality with no "dead spots." A small, hand-written "10" is typically inked onto the top right corner of the back of the headstock.
• Electronics: It comes factory-equipped with coveted 57/08 pickups. These vintage-voiced humbuckers were wound using proprietary wire machines from the 1950s to replicate authentic PAF tones.

Key Indicators of the Gray Black Finish

• Translucent Dark Grays: The stain applies deep charcoal and trans-black hues directly into the 10-Top flame maple grain lines. This maximizes the 3D optical effect of the wood figure.
• The "Faux" Natural Binding: The exposed maple edge is left unstained, creating a sharp, clean contrast that acts as a natural frame around the translucent dark body.
• Opaque Back and Sides: While a color like plain Charcoal typically features a natural wood back, the factory Gray Black finish package for this era finishes the mahogany back and sides in solid black.

This piece was also signed on the Rear of the headstock by Paul Reed Smith himself.
