Have you ever seen this?

Just bought that off a guy. Sounds nice except some strange scratching noise when turning off the fast switch.</p>

Im wondering if this is original, or some home made story. Ive never seen a 760 looking like this. Also i've heard that the 760 are really loud, but this one doesn't put out that much of a volume.</p>

Also i have another question. I tried this with a tube guitar top, and it sounded wonderful. Just wondering if there is any risk of harming the elements in the leslie. I mean since the leslie doesn't have that much output per se. It contains a 15" woofer so you would think that it can take some extra volume. I read somewhere on this forum that there is a risk of blowing up the treble speaker (horn) it you're using an external amp.</p>

</p>

Any tips is greatly appreciated!</p>

At first I was thinking homemade cab on that... but it looks to have the original handles and bumper rails (and logo, obviously.) So I'dguess that's a 760 chop: maybe somebody couldn't quite fit it into their car to take to the gig, so they just shortened it up a little. This would explain both theapparently-reduced height and those horizontal braces. A stock 760 will measure over 45" from the floor by comparison.</P>


I too have found that if you can present an overdriven signal to the 760's input, you can essentially use it like a PA, i.e. it will just amplify the saturated signal. I did this with an M3, by overdriving the M3's internal (tube) amp - got a nice warm overdrive if not Jon Lord mayhem. But others have had different luck trying this - I think it may have to do with how the signal is tapped off the M3. You do have to be careful of the Jensen treble driver if you do this. The nice thing is you have trim pots on a stock 760 that let you choke the main volume off to a safe level. Then you can just mike the Leslie for gigs.</P>


hope this helps-</P>

When I go small I use an 860 which also is a twin rotary solid state model. I use the overdrive on a Hammond Suziki clone and it sounds OK. I alwaysuse at least a little overdrive and it seems to warm up the sound of the solid-state amp. But that is just me.</P>


Whenever you start pumping clipped signal into a leslie there is some risk. </P>


My 860 is loud but sometimes I need a little more stage volume. I mic the lower rotarsometimes both rotars and send to the Power mixer I use for my other keys and the 2 big 3 way cabinets Ihave on stage. Set the leslie further back from your other speakers so you can mic the front without feedback. Otherwise there are some doppler phase issues. ... but that is just what I do. I'm no expert.</P>

The treble driver is 40W, so if you don't feed it more than that, or bypass the crossover which keeps the lows out of it, the jensen should be okay.</p>

As for volume, there are THREE volume adjustments. Look in the back of the metal panel, to the left of the panel are thre screwdriver sized holes.</p>

With a flathead screwdriver they can be adjusted. The bottom one is the INPUT level, this is the amount of volume via the active crossover.</p>

After the crossover it heads to the other two holes... the middle one is the 35W treble amp and the top one is the 55W bass amp.</p>

The idea is to avoid the nasty solid state distortion... so you put it at the highest volume you want without distortion using those three adjustments. Once you've got it without distortion and with the preferred balance between the bass and treble, you use the one on the crossover as the master volume control.</p>

I've actually permanently changed the pot to have an external knob so I can adjust volume at will depending on the time of day.... </p>

Thanks for the replies! I tried adjusting the volume today at rehearsals, but the screwdriver was too small.</p>

Can you mess with this stuff while the organ and leslie are switched on, or is there a risk of damaging anything?</p>
