When I sold my Hammond Organ, I kept my Leslie 145 speaker cabinet. And part of the payment for the organ was a Leslie Combo Pre Amp.
This will allow me to play my midi keyboard/computer through the Leslie 145. It will also allow me to change speeds on the leslie with a foot switch. I’ve got some good virtual tonewheel organ instruments on my laptop, so I’m interested to hear how it sounds through the Leslie speaker.
I’ve got a 6-pin leslie cable coming from California, that I won on an ebay auction. Once that gets here, I’ll be able to test it out, and I’ll let you know how it sounds.
