The Custom 24 is the quintessential PRS guitar. This iconic instrument was the first model that Paul Reed Smith brought to the public at PRS Guitars’ first Winter NAMM show in 1985 and has been a top seller ever since. Played by internationally touring artists, gigging musicians, and aspiring players, the Custom 24 features PRS’s patented Gen III tremolo system and PRS 85/15 pickups with volume and tone controls and a 5-way blade switch. 85/15 pickups were personally designed by Paul Reed Smith to offer remarkable clarity and extended high and low end.
The Custom 24 is the original PRS. Since its introduction, it has offered a unique tonal option for serious players and defined PRS tone and playability.

The Custom 22 is a classic workhorse with all the tones you’ve come to expect from your PRS with a distinctive midrange and clarity thanks, in part, to its 85/15 pickups. These pickups are wired for our 5-way blade switch, which offers a dual humbucker option (see switching positions below). The Custom 22 also features a PRS patented Gen III trem and comfortable solid mahogany pattern neck.
