A High-Quality, Musical Effects Processor

Many manufacturers can build boxes full of effects. But creating a compact and affordable multi-effects processor that's truly musical is a different story. The BOSS VF-1 draws upon the massive effects know-how of BOSS, Roland and COSM engineering to deliver great-sounding, supremely useful stereo effects for a wide range of professional and semi-professional applications. It starts with true 24-bit converters and 30-bit internal processing, then gives you 400 effects Patches ranging from guitar and bass multi-effects to COSM-based Guitar Amp Modeling, keyboard multi-effects, high-quality vocal effects, DJ/groove-oriented effects, extensive reverb, delay, and chorus processing derived from the acclaimed V-Studios, and even COSM-based Mic Modeling.

Perfect for a Variety of Applications

The VF-1's wide range of high-quality effects makes it perfect for project and home studios, keyboard rigs, guitar rigs, live sound, DJ/remix applications and more. Connectivity includes a high-impedance Guitar input jack on the front panel, and stereo inputs and outputs (switchable between +4/-10dB) on the rear panel. It also includes a coaxial Digital output for all-digital connection to recording and mixing products like the V-Studios and V-Mixers. A Category Search function and icon-based display permits quick navigation in the studio, while optional footswitch and expression pedal connection makes the VF-1 well suited to live performance.
