The 301 dl Dynamic Lo-Fi Echo is a delay pedal from Korg's ToneWorks line, made in the 1990s. It is a dynamic, lo-fi echo and delay with up to one second of maximum delay time, and its character comes from the ability to shape the frequency response of the echoes: you can adjust the brightness or darkness of successive repeats, along with predelay and more1. It is out of production and lives on the used market1.
Controls and presets
The pedal's most distinctive feature is how much it packs behind a small panel: a toggle switch lets you adjust eight parameters with just four knobs1. That means each knob does double duty, and the toggle selects which parameter set you are editing.
A Program footswitch lets you toggle back and forth between two saved preset settings1, so a player can keep two different echo sounds ready and switch between them with a stomp.
"There's even a Program footswitch, which lets you toggle back and forth between two saved preset settings."
Inputs and use with other gear
A Hi-Lo switch on top allows you to use both instrument and line level inputs1. In practice that means the 301 dl can take a guitar straight in, or sit with line-level gear such as an effects loop or studio source, which was not a given for pedals of its era.
Where it came from and what reviewers said
Pedal of the Day, reviewing the pedal in July 2026, called it a "sleeper gem from the 1990s" and summed up its verdict this way1:
"Pretty advanced stuff for a mid-90s effects pedal, and it still sounds amazing today."
The 301 dl is no longer in production. Players looking for one will be shopping the used market1.

Questions
What does the Korg ToneWorks 301 dl do?
It is a dynamic, lo-fi echo and delay pedal from Korg's ToneWorks line. You get up to one second of delay time, and the lo-fi character comes from adjustable frequency responses of the echoes, meaning you can shape the brightness or darkness of successive repeats. A toggle switch lets you adjust eight parameters with just four knobs, and a Hi-Lo switch accepts both instrument and line level inputs.
How long is the delay time on the Korg ToneWorks 301 dl?
The maximum delay time is one second, which covers most rhythmic and ambient echo work from a compact pedal of its era.
Can the Korg ToneWorks 301 dl save presets?
Yes. A Program footswitch lets you toggle back and forth between two saved preset settings, so you can keep one echo sound and switch to a second one mid-song without turning knobs.
Does the Korg ToneWorks 301 dl work with line-level gear?
Yes. A Hi-Lo switch on top allows you to use both instrument and line level inputs, so it can sit in an effects loop or handle other line-level sources as well as a guitar straight into the front of an amp.
Is the Korg ToneWorks 301 dl still made?
No. The 301 dl is out of production. Pedal of the Day's 2026 review notes the reviewer would have to search the used market to add one to a permanent collection, which is where players look for it today.
