I'm on the hunt for pedals and effects that use the reticon SAD 1024 bucket brigade chip.
My previous post was for the EHX slap-back pedal which also used this chip
Many of the early EHX pedals appear to have used the SAD 1024.
One such is the Deluxe Electric Mistress.
Versions 1 (1978), v2 (1979) & v3 (1981) used the reticon SAD 1024 delay
Version 4 & version 5 used the reticon RD5106A bucket brigade device. It had its own clock driver.
Its interesting that the reticon SAD1024 is a dual 512 stage delay &
the RD 5106A is a 256 sample device.
Notice the "icehocky puck" style knobs.
The Deluxe Electric Mistress is a iconic flanger. It has been reissued in the more compact "XO" chassis. In addition
to the analog filters, the Deluxe Electric Mistress features a
Filter Matrix for adjusting the sweep of the flange.
The Electric Mistress was designed by David Cockerell. David had worked for
EMS, where he designed the the Synthi
Hi-Fli. He also designed the Small
Stone phaser and Micro Synth.
These were based on the
Hi-Fli.
The Deluxe Electric Mistress was designed by Electro Harmonix engineer Howard Davis (who also designed the Deluxe Memory Man).
These pics are of a Deluxe Electric Mistress of I think 1979.
The PCB is labeled EH5150 B or C???
I'm inclined to think this is a V2 EH5150C.
The V3 has a green case.
Not exactly clear.
The power supply is 120V. There is an internal transformer held in place with two screws.
The case measurements are: 170mm x 200mm x 38mm.
ICs used:
1x LM78L. This is a linear voltage regulator.
1x 4558. Its a dual general purpose Op Amp
1x SAD1024A: BBD chip
1x LM324: Quad Op Amp
1x LM311N : Voltage comparator
1x 4013BE : CMOS Dual flip flop
Transistor: 1x 2N5087
Anyway, the Electric Mistress was used by David Gilmore of Pink Floyd.
He got his Electric Mistress V2 in 1976 or January 1977. It was used on the Animals Tour and I think the Pulse Tour in 1994. ?? You can hear it on many recordings like "The Wall"
Andy Summers of "The Police" is another notable user. Listen to "Do Do Do Da Da Da" or "Driven To Tears"
I found this old ehx pedal. It's a slap-back style echo. Model EH-4700.
Slap echo or slapback is a single echo resulting from sound bouncing off reflective surfaces.
Like when you clap your hands and listen for the echo in a large empty hall).
I understand that the Slap-Back pedal was one of EH's first forays into the smaller delay unit market.
She is pure analog and needs 18v to work, using either two 9V batteries or a 18V PSU.
I was initially drawn to it as the pedal uses the hard to find Reticon SAD1040 delay chip which is a bucket brigade IC. The Reticon can be found in the Serge WAD which is my favourite effects unit.
The Slapback delay is limited to 80ms. Just right for thickening guitar, bass guitar and other
instrument tones.
A distinct repeat-echo is added to the original sound resulting in a
very live sound similar to what you would hear in an auditorium.
The PCB is held in place by the Bend pot. So I was unable to remove the board to get a better look.
Thus these pics from the sides.
The pedal is uber simple.
Just two controls : a large 'blend' knob and a switch to turn a filter on or off.
The BLEND control is good for mixing wet and dry signals. The FILTER is turned on with a switch.
I think its a low pass as it seems to be good for cutting out hi frequencies.
There are standard 1/4" TRS connections
It's not versitle to replace your Memory Man
or other delay but is the perfect little pedal to use in tandem with
something like that to give you some varying delay tones.
I only have the first version but there seems to have been two other versions.
The Stereo Slap-back Echo edition, and the Slap-back Echo with Full Double Tracking Effects.
The Stereo Slap-back Echo edition, featured a DIRECT OUT output jack and a
power indicator LED. There one of only 2 small EH pedals that ever used LEDs. The other unit was the small clone
Both units used the
Reticon SAD1024 delay IC.
The Slap-back Echo with the Full Double Tracking Effect had a delay that was switchable between 50 and 100ms. The BLEND control was
retained and the FILTER switch was replaced by the MS DELAY switch. It
was produced around 1979 and used the Panasonic MN3005 delay IC.
EH seems to have replaced the Reticon chip with the Panasonic in nearly all of their effects. According to the net, the Panasonic chip was capable of doing the same delay effects, but with
better bandwidth and less noise.I kinda like the reticon though.
I'm addicted to bucket brigade chips. Ever since I first heard a Serge WAD I can't get enough of their beautiful sounds. The WAD used the Reticon SAD1040.
BBD (Bucket Bridge Delay) ICs are great for effects like reverb, vibrato, chorus, phasor, flanger & echos.
My favourite Chorus pedal is the Boss CE-1
Created in 1976 when Roland founded Boss, the CE-1 is viewed as one of the
progenitors of the chorus/vibrato effect & is timeless.
It uses Panasonic MN3002 BBD chips. They are single 512 stage IC's.
They also featured in the 1975 Roland Jazz Chorus.
Yes , It's a guitar amp.
Another chorus pedal that I think is worth checking out is the Electroharmonix small clone.
EH4600.
From 1979 to early 1981 it seems that, EH used either the MN3007 delay chip or the
RETICON SAD1024.
The sonic differences are subtle. The SAD1024 version has been described as more “watery” sounding, adding a
slight “boost” to the signal, while the MN3007 allows higher levels and
less noise without signal clipping. The most sought after unit is
the 1024 one, mostly because this was the version used by Nirvana’s Kurt
Cobain on “Nevermind” and the
“MTV Unplugged” sessions.
The vintage units have a clear and smaller (3mm) LED versus the red
and larger (5mm) LED in the reissues. Also, the originals don’t have a
dash mark (-) separating the words FULL and CHORUS.
The reissues have FULL-CHORUS (with the dash) written on it.
The MN3007 is a 1024 stage long delay low noise BBD that provides a signal delay of up to
51.2 msecs. They seem pretty easy to get on ebay.
It's found in many popular pedals like the DM-1 and CE-2 & CE-5 by Boss, the MoogerFooger 108M Clusterflux, theMemory Man by Electro-Harmonix, AD-999 by Maxon or Analog Delay by MXR.
Moog Delays (MF104)used MN3008 chips ??? I think.
The 3008 chips are very hard to get these days. Thus those MoogerFooger delays are not made any more & go for ridiculous prices on Ebay. They are a single 2046 stage chip.
This rare Korg 5 channel mixer uses a single MN3005 to produce the delay.
