As Mike O'Malley previously stated, I just plugged a RCA to 1/4" cord right into the RCA jack on the expression pedal housing of my M-3 (after removing the back), ran the cord through the power cord hole, re-installed the back, plugged the 1/4" end directly into a Electro Harmonix Lester G Leslie pedal, then connected the stereo outputs of the Lester G into 2 separate Fender KXR amplifiers topped with Motion Sound Pro-3's spaced across the room from each other and holy smokes.......you've basically got panning Leslies. Electro Harmonix nailed the Leslie sound for around $200 also......I am still blown away at how easy & cheap I got my M-3 to scream even with just the Lester G right into the PA.

That RCA jack was a phono input, so if you use it as an output there's a resistor that you should remove to get the full range sound.

Thanx for this info....I wondered if doing this would work!!

Mark, Thanks for posting this. Just acquired an old Hammond model G. Someone appears to have already done this modification. I’m new to owning a Hammond and not afraid to work on it. Although, I have tons of questions and the technicians here in Nashville are not very helpful

On an Organ I have of this vintage, I put a Line Out from the Preamp and a Bypass Output on the Rheostat Box.

on M-3s there is an RCA jack on the expression pedal housing that says "radio input"... there is a low level signal there that I boost with a ProArt Preamp and send the 1/4 in output to my converted 147 Leslie or my Motion Sound Pro3T...

That'll work.. I vaguely remember there's a little resistor on the other side of that plug that should be taken out to get a full range signal

Yes. I actually took a signal from the preamp as you suggested and hooked it up to 2 Direct Boxes and the Leslie Digital Pedal. I was able simulate the sound Leslie 122 and 147 Cabinet for less than $600.

PLZ!! I have an old X-66 with NO OUTPUT. I'm going to replace the AC Power cord first and see if that does anything. What would be next other than trash the thing?

hello...great video info.....Question: Have a A105....want to hook up my 122 that has both a vintage 428 and a type 3M echo unit that was on my other C3....I see how its connected to the C3 but not sure connecting it to the 105 that has the speakers in it.....I assume I connect to the 58amp, but not sure....Any help would be appreciated.....

Thank for your helpful video and sorry for my ignorance: Have I to simply solder an instrument/guitar cable to the two black/red "G" terminals and plug the jack to the mixer/amp/PA system? Thanks for the kind answer you'll want to give me 🙂

Using G and Ground is usually too hot for effects such as the Neo vent. I've made attenuator circuits in the past to reduce the level. I did recently read the you should use both Gs and the Ground with an 1:11 matching transformer like the one from a 122xb to balance the signal. What's your thoughts?

@MarcMcElroy 9 ай бұрын

your organ comes with a built in 20db cut on the output, it's the soft normal switch, try that first.

@Lamster66 9 ай бұрын

@@MarcMcElroy Indeed you could, the attenuation works very well though Actually the problem I'm currently having is getting bite and grind usually you can adjust the variable capacitor on the swell but it was defective. I've sorted that dismantled it and cleaned it that now works and you can set that up correctly. It doesn't matter how much you try to overdrive it, it won't. I suspect there a weak valve in the AO28 but currently it's sou ding pretty good, just laking drive.

you can't they're not that loud, maybe 12 watts, compared to a 35-50 watt Leslie it's no match.

@MarcMcElroy 5 ай бұрын

It's audio, not electricity. If you're familiar with electricity think if it like a 240v curcuit, two different kinds of hot, and a ground, when you hook onto one hot, you get half the voltage.

yeah..maybe you make "ok" guitar amps, but you're junkin out some pretty cool stuff man. been there, done that, now have exactly one dozen Hammonds, mostly re-capped CORRECTLY, and gone thru, from a 49 M, to a 62 A-100, some modded, some not. 5 Leslies, again, some modded, some not. I am mainly a guitar and bass player, and have a bunch of amps as well.(Fender, Traynor, etc..not a Marshall fan tho) i think the purpose built amps just end up sounding better..after cappin, etc. LOOOOOOVE the Hammond sound..too cool to tear em down.imho, unless it was a real roach.
