Hey Daz I did my adjustment yesterday and i can't believe the increase in
both volume and distortion. And you are correct with regard to the
registrations. I normally use 888800000 and this is heaven. Cut back to
666600000 and it's clean for a Whiter Shade Of Pale cleaner sound, but still
bloody loud.

Hi Bob,
(snipped from previous mail)
I have used the following procedure myself in the past to produce
excellent
results. I was shown this procedure by a friend of mine who hired his C-3
to Keith Emerson when he came to the UK a few years ago. Keith liked it
so
much he wanted to buy it, Dave said NO WAY! She is my baby.
I wrote the procedure down for future reference:-
It works on the following organs with the AO-28 amp
B-3
C-3
RT-3
A-100
M-3
Firstly select the A# (console models) key on the upper manual, set the
drawbars to 80 8808 008. Expression pedal fully depressed. Turn vibrato
and percussion OFF.
If you use the pedals pull out the 16' to position 8.
The preamp drive level is set by adjusting the trimmer capacitor that is
behind a removable plug on the cover of the box containing the swell
capacitor. The preamp should be set to fully clockwise to start with.
Turn all the Leslie controls (volume) full up.
This next step requires two people:
One person should play a full 5 finger chord in the centre of the upper
manual, and the bottom C of the pedals.
The second person should now begin turning the trimmer counter clockwise
NO
MORE THAN ONE TURN. The organ should now be getting louder but not yet
distorting. Turn further counter clockwise slowly until distortion
starts.
For the real dirty Hammond growl the final setting should be 1/8th of a
turn
more than the point where it starts to distort.
DO NOT INCREASE TOO MUCH IT WILL CAUSE PROBLEMS! Mainly with overheating
of
the drivers.
The final setting should be approximately 1-1.5 turns open on most organs.
Now the test!
If you have adjusted for maximum distortion at max volume, the distortion
can be reduced by pushing in the drawbars slightly. The result should
then
be very clean sound but still very loud.
When complete you will have distortion on demand by the drawbar levels!!
No
need for add-ons.
Organs with the Trek-11 Preamp should be adjusted in the same way, but the
drive level is adjusted with the volume pot attached to the expression
pedal
control arm. Simply loosen the screw and use a small screwdriver to turn
the pot within the arm - DO NOT REMOVE THE ARM - all other adjustments are
the same.
Now sit down, play and bask in the nasty growling beast of a sound you
have
just created!
HTH
Daz.

Hey,
What screw are we talking about to increase growl? Bob
