The Leslie 760 (or 770, the same finish to look as 122 / 147) Leslie is a great "classic", as are 122 and 147. I use it with a C-3.
The only difference is a more powerful amp, but transistors (nearly 100 W). The sound is clear and still warm.
The same size as her sisters 122/147, just a little higher (wheels), finish makes it less fragile during transport. THE scene is Leslie!
Easy to use, it allows (thanks to the pedal combo) to send any instrument (synth, organ, guitar) in the amp.
Less grain than the 122 or 147 pushed into a corner, but fishing and more. A small tube preamp, and it was very difficult to make a difference ..
And you can set separate bass and treble (boring to do, but we do it once and for all, except live!)
However, it gives a little less acute than 147, which penalizes the "turning his', instead, it crushes the other cabins in the bass!
Already, it's a real leslie. Then it's a "classic" (same HP, same mechanics, same layout as the 122/147).
A few months ago I use it with a 122. A reference in the classic range, with 122, and 147. Only the amp that changes in trasistors, which colors the sound less. But hey, what fish! And what a sound! It changes a Elkatone or more!
My ranking: a notch below the 122 and 147 for its "cozy", lacks a bit of brilliance, but with more points anyway (solidity, reliability, power, bass). The best cabin transistors. The cabin is ideal for the stage.
