Paul Hindmarsh demonstrates the Multipass delay in the Line 6 DL4 MkII delay pedal. Paul is playing his custom Yamaha Pacifica guitar and the DL4 MkII is routed into a pair of Princess amplifier models in a Helix Floor amp and effects processor. Multipass is a multi-tap delay with a gently swept band-pass filter adding a touch of coloration.
