Analog Delays Every Guitarist Should Try

Analog delay represents one of the most characteristic effects in electric guitar history. Unlike digital delays, analog ones use bucket-brigade (BBD) circuits that provide that warm, organic, and slightly degraded sound that defined entire musical generations.

David Gilmour of Pink Floyd made the Boss DM-2 legendary in songs like "Time" and "Run Like Hell." Its MN3005 analog circuit produces repeats that naturally blend with the original signal, creating psychedelic atmospheres unrepeatable with modern technologies.

The Evolution of Delay: From Tape Echo to Bucket-Brigade

Before the advent of digital delays, guitarists used tape echoes like the Echoplex EP-3 or Roland Space Echo RE-201. These mechanical devices naturally introduced distortion, flutter, and wow that characterized the vintage sound.

Modern analog delays recreate these imperfections through BBD chips that slightly degrade the signal with each repetition. This "flaw" becomes an asset, providing warmth and musicality impossible to achieve with digital surgical precision.

The 5 Essential Analog Delays

1. Boss DM-2W Waza Craft (€299)

The Boss DM-2W represents the perfect evolution of the legendary DM-2. Standard mode faithfully replicates the original circuit, while Custom mode extends delay time up to 800ms maintaining analog character. David Gilmour and The Edge continue using it for its unmistakable sound.

Features: Delay time 20-300ms (Standard) / 20-800ms (Custom), MN3005 chip, true bypass, 9V power.

2. Strymon El Capistan (€449)

The Strymon El Capistan perfectly emulates three tape echo icons: dTape (EP-3 style), Fresh (new tape), Worn (used tape). Advanced controls allow adjusting wow, flutter, and tape distortion. Radiohead and Bon Iver use it to create complex soundscapes.

Features: 3 tape modes, tap tempo, expression pedal input, stereo I/O, storable presets.

3. Way Huge Aqua Puss (€199)

The Way Huge Aqua Puss offers classic BBD sound in compact format. Designed by Jeorge Tripps, it uses MN3005 chips for delay times up to 300ms. Its ease of use and accessible price make it perfect for those approaching the analog world.

Features: Delay 40-300ms, MN3005 chip, Blend/Delay/Feedback controls, LED status.

4. Empress Echosystem (€549)

The Empress Echosystem combines 36 different delay algorithms, including accurate analog emulations. BBD mode perfectly recreates vintage chip behavior, while extended controls allow extreme customizations. King Crimson and Tool use it in studio and live.

Features: 36 algorithms, dual engine, MIDI, expression input, presets, true stereo.

5. Boss DM-101 (€399)

The Boss DM-101 represents the latest chapter in Boss evolution. Eight parallel MN3005 BBD chips guarantee extended delay times maintaining analog quality. Saturation control simulates magnetic tape saturation.

Features: 8x MN3005, delay up to 1200ms, adjustable saturation, tap tempo, true bypass.

Analog Delay Equipment

Iconic Bucket-Brigade Chips

• MN3005: De facto standard, used in DM-2, Memory Man

• Marshall JTM45: Perfect for vintage rock and blues delay

Analog Delay Curiosities

What's the main difference between analog and digital delay? Analog delays use bucket-brigade chips that naturally degrade the signal, creating warmth and musicality. Digital ones offer precision and unlimited delay times but can sound cold.

Why are MN3005 chips so sought after? Panasonic ceased production in the '80s, making original chips rare and expensive. Their unique sonic character is difficult to replicate with modern components.

How do you properly set an analog delay? Start with Feedback at 30%, Delay Time at 25%, Mix at 20%. Gradually increase feedback to the oscillation limit, then reduce slightly to find the sweet spot.

Are analog delays noisier than digital ones? Yes, BBD circuits naturally introduce noise and clock whine. However, this "flaw" contributes to the vintage character appreciated by guitarists.

Which analog delay did David Gilmour use on "The Wall"? Mainly Boss DM-2 and Binson Echorec 2, often cascaded to create complex delays. The DM-2 handled short delays, the Echorec long and atmospheric ones.
