Reverbs and Echo

All of the equipment listed in this section is available for use at Albro Analog Audio Studio.


These are two of the plate reverbs at Albro Analog Audio Studio.
The larger one is the Ecoplate I (4′ X 7′) and the smaller is the Ecoplate II (3′ X 6′).
These were designed and manufactured by Jim Cunningham,
the premiere echo genus who owns Studio Technologies.
The illustration is from ‘Recording Engineer / Producer’ magazine dated February 1981. Mr. Cunningham still offers advise and replacement parts for these units.

EMT 140 DS

EMT 140 TS

This is the third plate reverb available for use at Albro Analog Audio.It is the original EMT Plate Reverb. These are no longer made and rumors are because the company, EMT-Franz, could no longer obtain the high carbon steel that gave the plates their famous sound. This unit is about 4 ft X 8 ft and weighs almost 400 lbs. This particular plate reverb came from Sound City in Van Nuys, California. This is where ZZ Top had been recording.

AKG BX 20-panel


The AKG BX-20e is the mother of all spring reverbs. This monster is 44″ high, 17″ wide and 20″ deep. This unit does not sound ‘springy’ at all. It is a stereo unit that produces a lush and full sound.Smooooooth  Use a 5ms to 10ms Delay and add a touch of this spring reverb to the return of a plate reverb for a nice effect. Note the size of the unit next to a 6ft grand piano.


The AKG BX-10 is the middle size of AKG’s line of spring reverb units. This is a two channel unit also which can be used by itself or combined with other effects. Not as ‘Lush’ as the BX-20 but morenatural than other spring reverbs. Note the size of the unit setting on a 6ft grand piano.

The AKG BX-5 is the smallest of AKG’s spring reverb units. Some artists like them for ‘Surf Guitar’ and the a 50’s type of sound. Ihave two in the rack just in case.
The Demeter RV-1 Real Reverb has a raw tone that is unique. This is a two channel unit. I like to take channel one direct to the board and delay channel two by 5ms panned to the opposite side.

The Orban 111 is an old school dual channel spring reverb from the 60’s. There are two of these in the rack which can be run in stereo with one channel delayed.  This setup delays a different waveform which can be eq’ed differently and creates a fuller sound.

The Roland SRE-555 is the studio version of Roland’s tape echo units. A lot of ‘seasoned’ guitar players swear by the road version (Roland SRE-501). It has so many settings I just love to experiment. I have one in the rack and a spare.

If the artist can not find the sound they want with the above effects units, then there is a 10 ft high shower enclosure lined with ceramic tile. This can be used with a speaker and microphone for that ‘Echo Chamber-like sound’ or with the artist inside with the water running for that ‘Special Vocal Sound’.
