Roland FV-2

Andy Summers had used a Roland FV-2 volume pedal with The Police.

He used this volume pedal to control the VCF filter on the Roland GR-300 guitar synthesizer. And with it he developed the distinctive swelling synth sound, which is heard on songs such as the bridge of "Don't Stand So Close To Me", the opening to "Secret Journey" and "O My God" to name a few.
