I have a 1964 Hammond A-100, no Leslie yet (The A-100 comes with an internal speaker), and I installed a 1/4 inch jack so I can also run it through a Roland KC-150 keyboard amp. I'm interested in getting that "overdriven" sound similar to what Keith Emerson got on ELP's first 3 albums. I can't afford a Leslie just yet, but I'm thinking there must be an effects pedal out there that will approximate the sound. Anybody out there have suggestions on what kind of pedal to get?</P>
I have done this mod/adjustment with every Hammond I've had with good results. The AO-28 responds much better to this tweek than an AO-29 in an M series Hammond. Another thing to try in addition to the preamp adjustment is the Boss RT-20 Leslie (rotary) simulator pedal. I bought one for my M101 which is connected to an Alesis Sumo 300 keyboard amp. I got decent results and am somewhat satisfied with it. At a street price of $200 it is not a cheap pedal. The RT-20 also has distortion if you choose to use it. Be aware that the pedal is very sensitive to adjustments and settings, less is more in other words. The distortion is OK, the choral (slow speed) is very good and the fast is a bit choppy. The farther away you are from your keyboard amp, the better the effect will sound in my experience.</P>
I have put my complete guitar pedal board in the loop and played with various overdrives. The Ibanez tube screamers work pretty well as does the Boss OS-2 (overdrive and distortion in one pedal).</P>
Re: How can I get that "overdriven" sound.
I'm in pretty much the same spot. I have a 1962 A-100, but I DO have a Leslie 147. I've been keeping the volume level down enough to keep it clean, but I also play in a Deep Purple cover band, and now I really want to raunch it up! I want to get my Hammond and Leslie to sound like the opening chords to Perfect Strangers. I looked around the back and found a trimpot on the back of the preamp, (opposite end of the one for the perc. cutoff), I tried to adjust it but found it was already "up all the way". So I was wondering, what the heck's going on, I gotta have more power than this"... Then I saw this. YES. Perfect. Gonna go print it out and grab a few rolls of dimes (I use them to hold the chord while I'm fiddling in the back).</p>
Re: How can I get that "overdriven" sound.
No problem, I already have that all done up.[;)] I use the echo switch to switch between the Leslie and the Marshall (well actually it's a big Road amp but it sounds really close).</p>
Just finished cranking it up, sounds awesome now but I think it was up a bit too high so I just turned down the volume a smidge on the Leslie's tube amp. Now I just gotta get the reverb to come out of the Leslie, gonna have to find and switch to Leslie kit #8444... I wonder where I can find one...[*-)]</p>
Re: How can I get that "overdriven" sound.
Hey H101,</P>
Thanks for the great tips. I picked up an overdrivepedal for starters. I haven'tstarted poking around inthe back just yet, but I intend to.Ihave a toddler running around the house, so I'll have to be strategic about when I do that. Thanks for taking the time to respond and getting me pointed in the right direction. </P>

Hey H101, how does this adjustment relate to the simple adjustment of the gain on the Leslie amp? (I'm running two 147-types) ...Sorry, I'm not exactly sure what I'm asking here... I guess the 147 amp is what overdrives the speaker, but adjusting the (Hammond) preamp lets you input an overdriven signal into the input stage on the Leslie amp? --What I'm after is being able to get a little crunch without knocking pictures off the wall in the house! It sounds like with this adjustment, I'd be able to turn down the gain on the Leslies and still have a little growl... or am I missing something here? Thanks in advance for your thoughts. cheers, TD</P>

TD,</P>
You got it, raunch without volume, the preamp does it most nicely. I don't like drivingmy Leslie to distort. I'm afraid of killing the V21. The Leslie control is more of a volume adjusment than a gain control if you ask me. What I think I hear when you really crank one up is the power section distorting, kinda likea black face Fender guitar amp.</P>
The sound you get by adjusting the trimmer cap in the Hammond's preamp is "The Sound"when you mash the exp. pedal. Think Keith Emerson tone when he is blasting chords.</P>
