X77GT with a 77P Leslie

[Guest]

I'm considering purchasing an X77GT with a 77P Leslie. I have always enjoyed the "ramp up/down" of the leslie speaker with other Hammonds/Leslie's. I tried playing the X77GT / 77P and wasn't able to get this to happen. Is there any way to get this combination to do this? I really like the way the X77GT sounds... HELP!

I would say it's partially possible but will probably take an experienced tech. This was a very unusual design and heavens only knows why they made it with no ramp up and down effect. Much of the problem lies in the organ with the leslie switches. They switch channels in and out which is why you never hear the speed change. Also, remember that it has a 6x9 drum rotor. If you're looking for the traditional B3/122 effect and sound, this won't do it.</p>

Following on from what George has said, the Rotosonic drum in the X77 cabs is single speed only. It's always on fast (like a throwback from the old 204/205/610 valve cabs). When you switch to slow, the treble horn slows down but the lower drawbars frequencies get switched to straight channels with an electronic celeste effect. So no wind up/down on the lower rotor at all. Why? No idea, perhaps they thought people wouldn't like the very slow speed changes of the Rotosonic drum.

With some (considerable?) effort you might be able to find a couple of leslies like the model 720 (or 710 if you don't mind the Rotosonic sound) and somehow wire them up instead of the X77P.</p>

There are some X77 experts around here that might know how this might be done.</p>

This is the one in Auburn, isn't it? The guy also has a beautiful Hammond Elegante with Leslie 540 and 720 and a Wersi Delta DX 500.

G'day John,</P>


As an X77GT owner let's see if I can shed any light on this one. The 77P is 4 channel cabinet, and Andy is correct in that the rotary channel consists of a single speed (fast) roto drum and 2 speed treble horn. In one of the stationary channels the cab incorporatesan electro-mechanical vibrato &amp; space generator to provide the chorale effect on the lower frequencies.</P>


Simply switching the "Celeste" tab on while the green Leslie tabs areon will not achieve the ramp up/down you are looking for, all that happens is all frequencies are transferred to the roto drum, away from the treble horn.</P>


However, if you turn both Celeste &amp; Chorus tabs on, again with the green Leslie tabs, higher frequencies will remain in the treble horn which will brake to slow and lower frequencies will transfer to a stationary channel with the electronic effects activated. You will however hear just a bit from the roto drum.</P>


Turning "Celeste" on while Chorus and the green Leslie tabs are off, will give you the chorale sound (slow treble horn &amp; electronic low freq.)without any interference from the roto drum. In this mode you may wish to split the effect by turn the lower green Leslie tab on. This will give you chorale on the UK &amp; Trem from the roto drum on the LK, not unlike the old B2/C2 split vibrato.</P>


Remember the ramp up/down effect is most noticeable in the treble horn, not the lower rotor, and while the 77P won't do the job precisely, my ears aren't diappointed. I should add I also own a 720 cab. and the effect is much the same, more noticeable in the treble horn.</P>


I'll agree with Andy, I don't think purchasers of a Hammond tonewheel of this calibre would have gone for a 2 speed roto drum, only because of the slow spin up time. Remember also the 77P is not the only Leslie model that uses electronics for low frequencies.</P>

Thanks to all of you... I'm impressed with your support. I guess what I need is a B-3 equivalent (B-3's are way to expensive). I really do like the "gospel sound". </P>

OK, go hunting for a C3, RT3 or A100, all B3's in different boxes, costing less money. Best value around if you don't mind the cabriole legs is an A102, most of which saw life as home organs. </P>

Re: X77GT with a 77P Leslie

An alternate approach would be to run the 4 balanced outputs of the X-77 through a small mixer so you can sum the outputs to one, and go through a standard Leslie combo pre amp and Leslie. The X-77 and its Leslie are quite an intertwined set up. The X-77 is not a B-3 substitute, but if you could get all of its sounds summed and directed through a standard Leslie, I believe it would be a great sounding set up.

I went ahead and did it... I found a C-3 for $850... but had to drive 9+ hours to get it.

Thanks again for all your help... :)</P>
