What is a Drum Echo?

Types of Echo Technology

There have been many delay/echo technologies over the years. Before dedicated delay effects were available, studio engineers used their reel-to-reel tape machines to produce echoes. Dedicated delay effects units such as the Echoplex and the Roland Space Echo also used magnetic tape for their echoes, though with less fidelity and stability than studio tape recording machines. Also in the early days of echo effects units came the invention of the oil can delay (which used an electrostatic-mechanical system to produce its echoes).

Later, with the advent of integrated circuit chips came analog bucket brigade delay technology, allowing smaller devices that were not prone to the mechanical wear and tear that their ancestors suffered from. Continued advances in technology led to digital delays that offered extended delay times and increased fidelity. Today, modern digital signal processing (DSP) allows for extremely high fidelity plus the possibility of carefully reproducing the rich sonic characteristics of older delay technologies. So among all these delay systems, where does the drum echo fit in?

The Birth of Drum Echo

The magnetic drum echo began as an effort to develop an echo technology that would be more sonically stable than tape delays, overcoming the wow (slow pitch variations) and flutter (rapid pitch variations) inherent in the tape-based echo units available at the time. To overcome those issues, Bonfiglio Bini, owner of Binson in Milan, Italy, and engineer Scarano Gaetano created a system using a balanced rotating metal drum with a stainless steel wire (the recording medium) wrapped around the drum’s circumference.

Their most famous product, the Binson Echorec, had a record head and four playback heads arranged around the edge of the drum. The playback heads were spaced so that (with head four as a quarter note reference) head one would have a 16th note delay, head two an 8th note, and the third head a dotted 8th note delay. Different combinations of active and inactive playback heads could be selected with a twelve-position switch on the Echorec’s front panel.

The Sound of Drum Echo

Binson produced several iterations of the Echorec over the years, including the Echorec 2, the Echorec Baby, and eventually even some six-head solid state models. Binson drum echo machines can be heard on several recordings from the 60s and 70s, but are most closely associated with Pink Floyd, thanks to Syd Barrett’s and David Gilmour’s inspired use of the units.

Magnetic drum echoes are famous for their warmth and for their harmonically rich and saturated sounds. This is due not only to the characteristics of the magnetic echo system, but also in large part to the many tube stages present in the most sought-after units. There were tubes in the input buffer, the signal mixer, the record and playback amplifiers, the tone shaping circuit, and the output mixing circuit.

    Hi Strymon

    Interesting post!

    You wrote: “There were tubes in the input buffer, the signal mixer, the record and playback amplifiers, the tone shaping circuit, and the output mixing circuit.”

    With the Volante’s analog components, are you emulating these tube stages and using DSP to create (and process) the repeats?

    I can’t wait to get one, but none of the Australian shops have them as of yet!

    Cheers

      @Daniel – We utilize an analog JFET and the DSP to emulate the each of these stages in Volante’s delay repeats.
