What it does

Harrison 3D Delay is a "free studio-grade stereo delay" from Harrison Audio, now part of SSL. It covers doubling and slapback through to evolving multi-tap ping-pong delays, and is a modern take on Harrison's older 3D Triple Delay.

Three taps: left, center and right delay taps, each individually timed, panned and given its own feedback.
Cross-feedback: you can feed signal between taps, for example from center to the sides or back, for more complex patterns.
Vintage character: modulation and damping controls recall classic digital rackmount delays.
Filtering and timing: adjustable HP and LP filters, tap tempo, BPM sync and delay-time controls, plus a wet/dry mix.
Display and presets: a Delay Tap Display Graph with click-and-drag panning, and 10 mix-ready presets such as Slapback, Ping Pong and Rock Echo.

It is free.

When to use it

3D Delay is a free, straightforward three-tap delay. SSL's own X-Delay adds a fourth tap, diffusion and de-essing, Valhalla Delay offers many more modes for a low price, and EchoBoy covers far more vintage styles. Pick 3D Delay if you want a no-cost stereo delay with independent left, center and right taps for doubling, slapback and ping-pong.

Best for: vocal doubling and slapback, wide guitar solos and synth leads.
Genres: pop, rock and electronic music, especially '80s-style productions.
Look elsewhere if: you want tape emulation, long modulated ambient delays or built-in reverb.
Standout: three separately panned taps with cross-feedback, for free.

What producers say

Early write-ups call it an easy, useful freebie.

Bedroom Producers Blog (2025): James Nugent wrote "I think it works great on vocals" and, with some modulation, "it's excellent on synths for some 80s character."
The Gear Forum (2025): one member said "this one IMO is worth adding to your arsenal" and found it "Rather easy to use, too."
