AP-WA Treble Booster

The BSM AP-WA is a medium gain Treble Booster designed to replicate the creamy, live tone of British guitarist Andy Powell from the early 1970s. Known for his work with Wishbone Ash, Powell's sound is characterized by twin harmonics and a distinct folk-rock vibe, particularly evident in tracks like “Ballad of the Beacon” and “Blowin’ Free.” This pedal works effectively with medium or low output PAF-style pickups, Mini Humbuckers, or P90s on mahogany guitars, allowing players to access a range of classic 70s tones. The AP-WA provides a boost that enhances clarity and warmth, making it suitable for both rhythm and lead playing.
