Line 6 DL4 Review

What is Line 6 DL4 ?

The Line 6 DL4 stomp box is an amazing modeler. Known to some as the “Green Box”, the pedal has 16 effects ranging from multiple echoes, delays and a looper. Each of the digital effects on the DL4 can be tweaked with a simple interface.

You will be able to set your delay times, number of repeats, adjust bass and treble on your delays and mix your signal from up from a dry signal to an unprocessed signal.

The DL4 has three stomp switches (labeled A,B and C) which can be programmed with whatever tasty effects you can come up with. The fourth stomp switch controls your loop.

Line 6 has added an input jack for an expression or “wah” pedal to control some of the effects on the DL4’s presets and also on your own, programmed sounds. It’s easy to set up and gives you more diversity with your range of sounds.

The DL4 boasts two inputs (left and right) and two outputs (also left and right). When you plug into the left input, it acts as the on or off switch. You can purchase the power supply separately, but the DL$ also runs on 4 size C batteries.

Here’s What It’ll Do For You

The Line 6 DL4 will clear up some of the clutter in your stomp box set up. The modeling capabilities will help you hone your tone much better than an array of different and separate pedals. Each of the stomp box’s presets model some well-known and renowned sounds ranging from Maestro’s EP echoes to Roland’s RE-101 Space Echo.

Not only will the Line 6 DL4 help you achieve some classic tones from some amazing developers, the stomp box gives you the freedom to style the tones to your liking. For each factory preset, you can dramatically change the way the DL4 handles your signal.

For example, you can use the Auto-Volume Echo preset, which acts as a fade-in swell and can act like you are turning the volume knob up and down on your guitar.

The Dynamic Delay preset can really give your tone an extra boost. It softens the echoes and repeats while you are playing, but the moment you stop playing, the intensity of the echoes and delays picks up.

As stated above, the delay can be tweaked so your repeats and echoes can have ranging treble and bass effects placed on top of them. This will help reduce some of the murky and messy sounds usually associated with heavy delays.

One of the favorites of the Line 6 DL4 is the Ping Pong effect setting. This specific delay utilizes two different channels of delay to make your sound seem to ping pong back and forth nice and smoothly. The delay can be timed to your liking by using some of the user interface knobs.

As well as having these killer effects and tones, the DL4 also provides the guitarist with the infamous Loop Sampler. You can record and overdub your riffs and chord progressions, then rip up some killer solos over them with the looper. The DL4 provides the guitarist with a variety of setting. You can play your riff or progression just once, play it at half speed or even in reverse!
