Line 6 DL4 MkII Delay Modeler Pedal

The Line 6 DL4 MkII takes everything players love about the original DL4 Delay Modeler and adds 15 new MkII delays drawn from Line 6’s HX family of processors. Together with the 14 original DL4 delays and the Echo Platter from the rackmount Echo Pro, that’s 30 delays in total. It keeps the original’s familiar knob and footswitch layout, and pressing the Legacy button turns it into a classic DL4. It’s built from cast aluminum to stand up to the road, and it’s smaller and lighter than the original.

Looping gets a major upgrade, with both a 4-Switch Classic Looper and a 1-Switch Looper that run in mono or stereo and can be placed before or after your effects. Onboard memory provides up to 240 seconds of recording time. An optional microSD card extends that to several hours and lets you store a loop, and in looper mode the Tap switch handles half-speed and reverse. An XLR mic input with its own level control lets you process and loop vocals or acoustic instruments through a dynamic mic.

The DL4 MkII also fits easily into modern rigs. It has stereo inputs and outputs, MIDI In and Out/Thru for program changes, continuous controllers, and MIDI clock, and USB-C for firmware updates and MIDI control from your computer. A jack accepts an optional expression pedal, two external footswitches, or one of each. Heavy-duty footswitches recall presets A, B, and C. Three bypass modes (buffered, DSP, and true bypass) let you choose how it sits in your signal chain, and a 9V power supply is included.
