Can someone advise me as to proper way to get signal from an M3 to a Leslie 147. I already have an external preamp with 1/4 inch input jacks for the Leslie.
The only diagrams I have found on the net are similar to this one: How to Install a Line out Jack on a Hammond M3 Electric Organ - wikiHow
It doesn't seem correct that I would tap in after the M3's amplifier just before the internal speaker effectively going through two preamp/amplifier stages.
There are a lot of wires back there and I'm new to the Hammond thing so literal answers would be more helpful than theoretical ones. (diagrams, pictures?)
