[HAM] What stomp box would best recreate the chorus /vibrato??

[Ralph Brown]

You may also try using the effects out channel on a mixer to get the blend.  I have heard of others who have inserted the vib box in place of the scanner with very good results.  I'm not sure how they did it, but it sounded good.

Kon,
   I have seen some units where the vibrato is the brighter of the two.
Hammond originally tried to keep them as tonally identical as economically
feasible.

Hi David.
I don't know if any particular chrorus / vibrato stomp box has been
specifically created to recreate the scanner chorus / vibrato effect
but you cap make a typical chorus pedal such as a Boss chorus pedal
which has a tone / treble cut control  sound more like the scanner
chorus  effect by turning down the treble on the pure vibrato signal as
long as the straight sounding part of the signal remains  bright and
unaffected by the tone / treble cut  control.
 
You might possibly need to open up the unit and then change the
grounding capacitor that rolls of the treble component of the pure
vibrato signal in order to approximate the scanner chorus  vibrato  /
straight signal tonal balance.
 
It is the bright  straight signal combined with the darker  vibrato
signal that gives the shimmering effect  to the scanner chorus effect.
 
One important aspect of the scanner vibrato effect is that the pitch
shifts  above as well as below  that of the straight frequency  thus
creating a richer sounding chorus effect. With my Boss  chorus pedal ,
the pitch only shifts above the straight frequency but it does not shift
below  the straight frequency so therefore  the chorus effect does not
sound as rich as the scanner chorus effect.
 
There used to be a Boss Vibrato pedal available many years ago but I
have never come across this pedal so therefore I do not know if the
vibrato signal  shifts above as well as below the straight frequency. If
it does do this then it might be possible to modify the pedal by
building a simple mixer stage to blend the straight signal with the
vibrato signal and to darken the pure vibrato signal and to brighten the
straight signal in order to approximate  the shimmering scanner chorus
effect.
 
All the best.

Lads. I'd like to know if you guys have in the past looked into what
stomp box or chorus unit
would best recreate hammond chorus/vibrato, thats my question.
I realize having mucked around with a guitar chorus unit that it is
simply not the same, similar yes but
definitely different and not good enough for my ears.
I'm sure the exclamation/reply fired back at me (from those who have an
opinion on everything) is likely to be why dont ya just use a scanner!?
That aint gonna help me for this project, thanks anyway.
 
Again, a scanner is not an option yet I'd like to best create to sound
of C1, C2 and C3 chorus.
Thanks in advance
