Line Out From A Hammond Console

MikeFulk suggests:

Run the hot for your line out through a 100 ohm resistor and 10mfd/50/NP cap in series...resistor to the "G terminal.....place a 100k resistor to ground from the end of the cap. The junction of the cap and 100k resistor is your line out.

  G o----/\/\/--------] [---+----o line out

                            /
                            \
                      100K  /
                            \
                            /
                            \
                            |
                            =
                       gnd  .

Another suggestion, incorporating a potentiometer, so that the (fairly hot) output of the Hammond can be padded down a little:

          1K         1.0 uf
  G o----/\/\/--------] [---+
                            |
                            /
                            \
                       50K  /<---o line out
                            \
                            /
                            \
                            |
                            =
                       gnd  .

Why the Capacitor?

In the above circuits, I'm not sure what the purpose of the capacitor is. If I had to guess I'd say it's to protect the organ's output transformer from errant DC (from a faulty "input").

I'm pretty sure the above circuits will work fine without the capacitor as long as you're careful about what you plug the line out into. (E.g., don't plug the output into a power supply.)

Line Out -> Preamp Pedal -> Leslie

If you're thinking about wiring up a line out so that you can use your LeslieComboPreamp to hook up your Leslie, you might want to think again. You'll most likely get better sound by hooking up the Leslie directly (as intended).

The ?SoulLive Sound

If you've heard the band ?SoulLive, you've surely noticed the drastically deepened bass coming out the organ. I've managed to duplicate this sound with a direct box (below) and an active crossover run into a large PA system. I used a cheapo Behringer CX2310 that I had, setting it to low-pass filter the signal at about 120Hz, and it worked great. Don't try to do this by cranking up the bass knob in the EQ section of your mixer- it'll sound like poo and probably mess up your speakers- you really need an active filter.

Direct Box Hookup

I use a direct box to run my Hammond into a large PA system. Make sure you use a direct box that has a transformer in it- these are usually the cheap ones. A box that is "active," which will probably require a battery or phantom power, is likely to give you problems. Hit the ground lift button, and hook the inputs of the box up to G-G. If you want to get the added harmonics and compression of the Leslie amp in there, you can hit the -20dB pad (and still the ground lift) on your direct box and wire it straight up to the woofer terimals inside the Leslie.
