The P-1800 PF R is engineered specifically for musicians with instrument amplifiers, particularly those using power-starved amps that need more current to perform at their best. Its Power Factor Technology provides a 45A peak current reservoir, giving your amp the headroom it needs for maximum efficiency and consistent tone, regardless of the venue's power quality. Combined with Clear Tone Technology, it provides a clean, consistent tone and improved dynamic response, making it perfect for guitarists and bassists who are serious about their sound. Clear tone technology also drastically reduces the noise floor making it a great addition to any studio where equipment performance is a must.
